Hi, I have to matrix (M_1, size 90x31 and M_2, size 90x130), i would like to subtract one column in matrix M_1 from each column in matrix M_2 and repeat this for each columns in matrix M_1 (31 times), and the result is a matrix ( there are 31 rows and 130 columns. Any ideas?
Thank you in advance.

What do the rows and columns represent? Do you have a 90 or 130 dimensional space? Or is each column just the location, like the x value along a number line? Have you seen pdist2() in the Stats toolbox?
