Octave:abbreviated-property-match
By default, the Octave:abbreviated-property-match
warning is enabled.
Octave:array-as-logical
If the Octave:array-as-logical
warning is enabled,
Octave will warn when an array of size greater than 1x1 is used
as a truth value in an if, while or until statement.
By default, the Octave:array-as-logical
warning is disabled.
Octave:array-to-scalar
If the Octave:array-to-scalar
warning is enabled, Octave will
warn when an implicit conversion from an array to a scalar value is
attempted.
By default, the Octave:array-to-scalar
warning is disabled.
Octave:array-to-vector
If the Octave:array-to-vector
warning is enabled, Octave will
warn when an implicit conversion from an array to a vector value is
attempted.
By default, the Octave:array-to-vector
warning is disabled.
Octave:assign-as-truth-value
If the Octave:assign-as-truth-value
warning is
enabled, a warning is issued for statements like
if (s = t) …
since such statements are not common, and it is likely that the intent was to write
if (s == t) …
instead.
There are times when it is useful to write code that contains
assignments within the condition of a while
or if
statement. For example, statements like
while (c = getc ()) …
are common in C programming.
It is possible to avoid all warnings about such statements by
disabling the Octave:assign-as-truth-value
warning,
but that may also let real errors like
if (x = 1) # intended to test (x == 1)! …
slip by.
In such cases, it is possible suppress errors for specific statements by writing them with an extra set of parentheses. For example, writing the previous example as
while ((c = getc ())) …
will prevent the warning from being printed for this statement, while allowing Octave to warn about other assignments used in conditional contexts.
By default, the Octave:assign-as-truth-value
warning is enabled.
Octave:associativity-change
If the Octave:associativity-change
warning is
enabled, Octave will warn about possible changes in the meaning of
some code due to changes in associativity for some operators.
Associativity changes have typically been made for MATLAB
compatibility.
By default, the Octave:associativity-change
warning is enabled.
Octave:autoload-relative-file-name
If the Octave:autoload-relative-file-name
is enabled,
Octave will warn when parsing autoload() function calls with relative
paths to function files. This usually happens when using autoload()
calls in PKG_ADD files, when the PKG_ADD file is not in the same
directory as the .oct file referred to by the autoload() command.
By default, the Octave:autoload-relative-file-name
warning is
enabled.
Octave:built-in-variable-assignment
By default, the Octave:built-in-variable-assignment
warning is
enabled.

warning is enabled.
Octave:fopen-file-in-path
By default, the Octave:fopen-file-in-path
warning is enabled.
Octave:function-name-clash
If the Octave:function-name-clash
warning is enabled, a
warning is issued when Octave finds that the name of a function
defined in a function file differs from the name of the file. (If
the names disagree, the name declared inside the file is ignored.)
By default, the Octave:function-name-clash
warning is enabled.
Octave:future-time-stamp
If the Octave:future-time-stamp
warning is enabled, Octave
will print a warning if it finds a function file with a time stamp
that is in the future.
By default, the Octave:future-time-stamp
warning is enabled.
Octave:glyph-render
By default, the Octave:glyph-render
warning is enabled.
Octave:imag-to-real
If the Octave:imag-to-real
warning is enabled, a warning is
printed for implicit conversions of complex numbers to real numbers.
By default, the Octave:imag-to-real
warning is disabled.
Octave:language-extension
Print warnings when using features that are unique to the Octave
language and that may still be missing in MATLAB.
By default, the Octave:language-extension
warning is disabled.
The --traditional or --braindead startup options for
Octave may also be of use, see ‘Command Line Options’.

If the Octave:missing-semicolon
warning is enabled, Octave
will warn when statements in function definitions don’t end in
semicolons.
By default the Octave:missing-semicolon
warning is disabled.
Octave:mixed-string-concat
If the Octave:mixed-string-concat
warning is enabled, print a
warning when concatenating a mixture of double and single quoted strings.
By default, the Octave:mixed-string-concat
warning is disabled.
Octave:neg-dim-as-zero
If the Octave:neg-dim-as-zero
warning is enabled, print a warning
for expressions like
eye (-1)
By default, the Octave:neg-dim-as-zero
warning is disabled.
Octave:nested-functions-coerced
By default, the Octave:nested-functions-coerced
warning is enabled.
Octave:noninteger-range-as-index
By default, the Octave:noninteger-range-as-index
warning is enabled.
Octave:num-to-str
If the Octave:num-to-str
warning is enable, a warning is
printed for implicit conversions of numbers to their ASCII character
equivalents when strings are constructed using a mixture of strings and
numbers in matrix notation. For example,
[ "f", 111, 111 ] ⇒ "foo"
elicits a warning if the Octave:num-to-str
warning is
enabled. By default, the Octave:num-to-str
warning is enabled.
Octave:possible-matlab-short-circuit-operator
If the Octave:possible-matlab-short-circuit-operator
warning
is enabled, Octave will warn about using the not short circuiting
operators &
and |
inside if
or while
conditions. They normally never short circuit, but MATLAB always
short circuits if any logical operators are used in a condition. You
can turn on the option
do_braindead_shortcircuit_evaluation (1)
if you would like to enable this short-circuit evaluation in
Octave. Note that the &&
and ||
operators always short
circuit in both Octave and MATLAB, so it’s only necessary to
enable MATLAB-style short-circuiting if it’s too arduous to modify
existing code that relies on this behavior.
By default, the Octave:possible-matlab-short-circuit-operator
warning
is enabled.
Octave:precedence-change
If the Octave:precedence-change
warning is enabled, Octave
will warn about possible changes in the meaning of some code due to
changes in precedence for some operators. Precedence changes have
typically been made for MATLAB compatibility.
By default, the Octave:precedence-change
warning is enabled.
Octave:recursive-path-search
By default, the Octave:recursive-path-search
warning is enabled.
Octave:remove-init-dir
The path
function changes the search path that Octave uses
to find functions. It is possible to set the path to a value which
excludes Octave’s own built-in functions. If the
Octave:remove-init-dir
warning is enabled then Octave will warn
when the path
function has been used in a way that may render
Octave unworkable.
By default, the Octave:remove-init-dir
warning is enabled.
Octave:reload-forces-clear
If several functions have been loaded from the same file, Octave must
clear all the functions before any one of them can be reloaded. If
the Octave:reload-forces-clear
warning is enabled, Octave will
warn you when this happens, and print a list of the additional
functions that it is forced to clear.
By default, the Octave:reload-forces-clear
warning is enabled.
Octave:resize-on-range-error
If the Octave:resize-on-range-error
warning is enabled, print a
warning when a matrix is resized by an indexed assignment with
indices outside the current bounds.
By default, the ## Octave:resize-on-range-error
warning is disabled.

automatically in literal matrices.
By default, the Octave:separator-insert
warning is disabled.
Octave:shadowed-function
By default, the Octave:shadowed-function
warning is enabled.

warning is enabled, a warning is printed
for implicit conversions of strings to their numeric ASCII equivalents.
For example,
"abc" + 0 ⇒ 97 98 99
elicits a warning if the Octave:str-to-num
warning is enabled.
By default, the Octave:str-to-num
warning is disabled.
Octave:undefined-return-values
If the Octave:undefined-return-values
warning is disabled,
print a warning if a function does not define all the values in
the return list which are expected.
By default, the Octave:undefined-return-values
warning is enabled.
Octave:variable-switch-label
If the Octave:variable-switch-label
warning is enabled, Octave
will print a warning if a switch label is not a constant or constant
expression.
By default, the Octave:variable-switch-label
warning is disabled.
