i have a problem. i have a cell A. cell A have 13*13 blocks (A{1,1},A{1,2},..., A{13,13})and every blocks have 8*8 pixels. i have matrix p 169*1 and matrix q 169*1.
i want to process them to find value A' = A*p + q.
example, A'{1,1} = (A{1,1}*p(1,1))+q(1,1).
next A'{1,2} = (A{1,2}*p(1,2))+q(1,2) and finally until A'{13,13}

p and q have 169 value, each value will be use to find A'.

i have mini program, but p and q, i have decide just one value and a just 4*4 matrix.
a=rand(4,4);
p=2;
q=1;
for x=1:4
for y=1:4
a'=a*p+q;
end
end
the different is A must 13*13 cell. p and q have 169 value because the A have 169 blocks.

out = A';
for jj = 1:numel(out)
out{jj} = out{jj}*p(jj)+q(jj);
end
out = out';
