meshgrid

Arguments

x, y, z

vectors

X, Y, Z

matrices in case of 2 input arguments, else 3-D arrays in case of 3 input arguments

Description

Create matrices or 3-D arrays.

Examples

x = -1:0.1:1;
y = -1:0.1:1;

[X,Y] = meshgrid(x,y);

for i=1:size(X,1)
  for j=1:size(X,2)
    Z(i,j) = sinc(2*%pi*X(i,j)*Y(i,j));
  end
end

surf(X,Y,Z)
