Subtracting two cell arrays, yielding a third cell array

Asked by Andrew on 4 Jun 2011

Hi,

I have two cell array of vectors; each cell in both cell arrays contains a 1 by 3 vector. For example,

A={[20 20 20],[30 30 30],[40 40 40];[50 50 50],[60 60 60],[70 70 70]};
B={[1 1 1],[2 2 2],[3 3 3];[4 4 4],[5 5 5],[6 6 6]};

How can I subtract B from A? For example, I wish to find:

C={[19 19 19],[28 28 28],[37 37 37];[46 46 46],[55 55 55],[64 64 64]}

Is there a way I can do this without stepping through each cell, converting them to numeric arrays using cell2mat, and then converting them back to cells?

Thank you very much for your time.
