So this might be quite simple and I just am having a brain fart...

My issue is that I am reading in data files to a 3dimensional array where I use hdrload.m to do this, First I load the header and data both as a 2D array then add them to the 3D array. However, some of my header files are dimensions:
187 x 84
and others are
186 x 84
So I am having issues combining these arrays to my 3D array since dimensions are different. So I figured an "easy" solution to this would be just changing the dimension of the 186 x 84 array to 187 x 84. However, I can not seem to find a way of doing this. Any suggestions?

Thank you!

if size(TheArray,1) < 187; TheArray(187,:) = 0; end

You may want to set the padding values to NaN rather than 0 to remind yourself later that these values don't represent real data.

yeah, I added a space at the end. Since it's the header files giving me issues, so the space won't be noticed.
