??? Error using ==> interp2 at 147 The lengths of X and Y must match the size of Z.

??? Error in ==> Untitled55 at 12 mesh (xi,yi,interp2 (x,y,A,xi,yi, 'linear'));

% Code here:
clc;
clear all
clf;
colormap ('JET');
A = [-10,5,10;0.2,1,2;1,6,2];%%%%
% I am sure, this error is here...I did not understand. How can I do?
