ndgrid

---

Rectangular grid in N-D space

---

Syntax

---

[X1, X2, ..., Xn] = ndgrid(x1, x2, ... , xn)

[X1, X2, ..., Xn] = ndgrid(xg)

Input argument

---

x1, x2, … , xn

vector: grid vectors as separate arguments.

xg

vector: grid vector for all dimensions.

Output argument

---

X1, X2, … , Xn

array: full grid representation.

Description

---

[X1, X2, … , Xn] = ndgrid(x1, x2, … , xn) generates an n-dimensional full grid by replicating each grid vector.

[X1, X2, … , Xn] = ndgrid(xg) In this scenario, the single grid vector xg is used for all dimensions. The number of output arguments determines the dimensionality n of the resulting grid.

Examples

---

M = {'apple', 'banana', 'cherry'};
N = {'blue', 'green', 'red'};
ndgrid(M , N)

[X, Y] = ndgrid(1:2:19, 2:2:12)
