FRANA Frame analysis operator
Usage: c=frana(F,f);
c=FRANA(F,f) computes the frame coefficients c of the input
signal f using the frame F. The frame object F must have been
created using FRAME or FRAMEPAIR.
If f is a matrix, the transform will be applied along the columns
of f. If f is an N-D array, the transform will be applied along
the first non-singleton dimension.
The output coefficients are stored as columns. This is usually
*not* the same format as the 'native' format of the frame. As an
examples, the output from FRANA for a gabor frame cannot be
passed to IDGT without a reshape.
Examples:
---------
In the following example the signal bat is analyzed through a wavelet
frame. The result are the frame coefficients associated with the input
signal bat and the analysis frame 'fwt':
f = bat;
w = 'sym8';
J = 7;
F = frame('fwt', w, J);
c = frana(F, f);
% A plot of the frame coefficients
plotframe(F, c, 'dynrange', 100);
