[Andrei Bobrov]

exactly what you want to do with the window 30x700?

Answer 1

just try to apply zero padding over the unwanted areas manually rather than using the bacproc commands

Answer 2

[Walter Roberson]

blkproc() is not supported in more recent MATLAB, having been replaced by blockproc().

The second argument to blkproc() should be your window size; in this case it would be [30 700]

blkproc() will pad your final 5 x 700 block with 0. It will not, however, be able to signal to you explicitly that it is a padded block.

If you want to use overlapping blocks, please see the older blkproc documentation such as can be found here

hai i have used the

B=blkproc(final2,[30 height],@(x)sum(x(~isnan(x))));

but i am getting the answer in a 21X1 matrix as all NAN,Inf,0

what is the problem i can't understand
