GABFRAMEBOUNDS Calculate frame bounds of Gabor frame
Usage: fcond=gabframebounds(g,a,M);
[A,B]=gabframebounds(g,a,M);
[A,B]=gabframebounds(g,a,M,L);
[A,B]=gabframebounds(g,a,M,'lt',lt);
Input parameters:
g : The window function.
a : Length of time shift.
M : Number of channels.
L : Length of transform to consider.
lt : Lattice type (for non-separable lattices).
Output parameters:
fcond : Frame condition number (B/A)
A,B : Frame bounds.
GABFRAMEBOUNDS(g,a,M) calculates the ratio B/A of the frame bounds
of the Gabor system with window g, and parameters a, M.
[A,B]=GABFRAMEBOUNDS(...) returns the frame bounds A and B*
instead of just the ratio.
The window g may be a vector of numerical values, a text string or a
cell array. See the help of GABWIN for more details.
GABFRAMEBOUNDS(g,a,M,L) will cut or zero-extend the window to length
L.
GABFRAMEBOUNDS(g,a,M,'lt',lt) does the same for a non-separable
lattice specified by lt. Please see the help of MATRIX2LATTICETYPE
for a precise description of the parameter lt.
