Problem 762. Matrix which contains the values of an other matrix A at the given locations.

Created by Julio in Community

If you have two matrices, which together give xc and yc coordinates into another matrix, eg : xc = [1 1 1; 2 2 1];

yc = [1 2 1; 3 2 4];

A = [6 7 8 9; 10 11 12 13];

Produce the matrix B which contains the values of A at the locations given in xc and yc. Thus:

B = [6 7 6; 12 11 9];
