Hi,
I have multiply PNG images in one folder with different images sizes (height and width), how can I use the padarray function so they will have the same canvas size (according to the bigger image) without resizing them?
Thanks a lot

Not hard. Just get the sizes of both, get the max, and figure out what to pass to padarray()
[rows1, columns1, numberOfColorChannels1] = size(image1);
[rows2, columns2, numberOfColorChannels2] = size(image2);
maxRows = max(rows1, rows2);
maxColumns = max(columns1, columns2);
and so on...

Because that's not the way to use padarray. Read the instructions. The inputs are the number of rows you want to add, not the overall total rows.
