I have a cell array A which has 1*5 cell, each cell has 12*1 doubles.
How multiply those 12*1 doubles with a MATRIX call B with 12*500 ?
Thank you

out = bsxfun(@times,permute(cell2mat(A),[1,3,2]),B); % out - 3D double array
or
out = cellfun(@(x)bsxfun(@times,x,B),A,'un',0); % here out - cell array (1 x 5)

for your data (MatFiles.mat):
A1 = cellfun(@(x)[x{:}]',A,'un',0);
out = bsxfun(@times,permute(cell2mat(A1),[1,3,2]),B); % out - 3D double array
or
out = cellfun(@(x)bsxfun(@times,x,B),A1,'un',0); % here out - cell array (1 x 5)
