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

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

blkproc() is not supported in more recent MATLAB, having been replaced by blockproc().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