MATLAB: How to rank data in a whole matrix

Question

Hi, I need to rank the data in a matrix but tiderank function does it for each column separately. how can I do it for all data in all rows and columns together? in a way that first cell of first column is first rank and last cell of last column is last rank.

Thank you

If A is your matrix, then

>> reshape(sort(A(:)),size(A))

should do it. You can use the 'descend' argument to the sort function if you wanted largest to smallest.
