Issue:
How do I concatenate multiple files into a single DataSet?
Possible Solutions:
If you are performing PCA on a multivariate image, you may need to construct a 3 dimensional (MxNxP) array where each image is MxN pixels and there are P images. An easy way to do this is using the Matlab cat() command.
>>mvimg = cat(3, img1, img2, img3);
Note the first argument = 3, this indicates the concatenation is occurring along the 3rd dimension.
