meshgrid

行列または3次元配列を作成

呼び出し手順

[X, Y] = meshgrid(x)
[X, Y] = meshgrid(x,y)
[X, Y, Z] = meshgrid(x,y,z)

パラメータ

x, y, z: ベクトル
X, Y, Z: 入力引数が2個の場合は行列, 入力引数が3個の場合は3次元配列

説明

行列または3次元配列を作成します.

例

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)
