At the moment the code i am using to upload multiple files and import the numeric data. This algorithm can be used to find matrix factorizations for an arbitrary convex loss function, if you want to do this under an additional nuclear norm constraint regularization. This means that a,b,c,d are 0 or 1 with only one 1 per row and column. Logical indexing steve on image processing and matlab. While other programming languages mostly work with numbers one at a time, matlab is designed to operate primarily on whole matrices and arrays. Functions in the image processing toolbox, as well as the matlab functions imread and imwrite, follow the convention that logical matrices are treated as binary black and white images.

If the size of any dimension is 0, then x is an empty array if the size of any dimension is negative, then it is treated as 0 if any trailing dimensions greater than 2 have a size of 1, then the output, x, does not include those dimensions.
