Hi
Suppose Pe_OPT is a matrix of size 115 200 and I want to rescale the part between VD>1901&VD<1919. VD is vertical axist of size 115 1, I am using following command which works for a single array but not whole matrix?
Pe_OPT(VD>1901&VD<1919) = rescale(Pe_OPT(VD>1901&VD<1919), 2.778e+07, 3.1005e+07);

range=VD>1901&VD<1919;
Pe_OPT(range,:) = rescale(Pe_OPT(range,:), 2.778e+07, 3.1005e+07);
