To add rows and columns in the start and at the end for a matrix

3 views (last 30 days)
Dear Researchers,
I need guidance to add rows and columns of ones/zeros in a marix.
i.e matrix should be 13642 * 25295, and matrix I obtained after some processing is now 12251 * 25293.
Now, I need to add lets suppose half of missing rows in start and half missing rows at the end, the same for columns.
Please guide me in this context, your suggestions will be highly appreciated. Looking forward to receive comments on it.

Just call it twice, one with "pre" and once with "post, each with the respective amount of padding required.
