meshgrid

Generate grid from vectors.
  • [X,Y] = meshgrid(x,y) generates from vectors x and y a full grid X, Y
  • meshgrid(x) is equivalent to meshgrid(x,x)

Examples

>> [X, Y] = meshgrid(-8:0.8:8)
Z = sin(sqrt(X.^2 + Y.^2)) ./ sqrt(X.^2 + Y.^2)
surf(X, Y, Z, struct('lineWidth', 0.1))

[X:21x21 double]
[Y:21x21 double]
[Z:21x21 double]
[ans:1x1 struct]

>> [X, Y] = meshgrid(-5:5)
Z = atan2(Y,X)
surf(X, Y, Z, struct('lineWidth', 0.1, 'pitch', 0.7, 'yaw', 0.8))

[X:11x11 double]
[Y:11x11 double]
[Z:11x11 double]
[ans:1x1 struct]
