Hello! I have a cell array of dimensions 1x1121, and I need the find the maximum value contained in this array. Since the max function only works on matrices, I was hoping to convert this cell array into a matrix. However, I keep getting an error on the dimensions when I use cell2mat. I have also tried using cell2mat(cellArray(1,:)) and as well initializing a matrix of the same dimensions to put the values (which are of type double into). Any input is greatly appreciated, thank you in advance.

MYCELL = {magic(3) magic(5) magic(6)}
mx = cellfun(@(x) max(x(:)),MYCELL)
mx has the maximum element for each individual cell. If you need the overall maximum, use MAX on mx.

Just to have an easy example to show you. No particular reason.
