: who

: who pattern …

: who option pattern …

: C = who ("pattern", …)

List currently defined variables matching the given patterns.

Valid pattern syntax is the same as described for the clear command. If no patterns are supplied, all variables are listed.

By default, only variables visible in the local scope are displayed.

The following are valid options, but may not be combined.

global

List variables in the global scope rather than the current scope.

-regexp

The patterns are considered to be regular expressions when matching the variables to display. The same pattern syntax accepted by the regexp function is used.

-file

The next argument is treated as a filename. All variables found within the specified file are listed. No patterns are accepted when reading variables from a file.

If called as a function, return a cell array of defined variable names matching the given patterns.
