MATLAB Function Reference |

Generate arrays for multidimensional functions and interpolation

**Syntax**

**Description**

```
[X1,X2,X3,...] = ndgrid(x1,x2,x3,...)
```

transforms the domain specified by vectors `x1`

,`x2`

,`x3...`

into arrays `X1`

,`X2`

,`X3...`

that can be used for the evaluation of functions of multiple variables and multidimensional interpolation. The `i`

th dimension of the output array `Xi`

are copies of elements of the vector `xi`

.

```
[X1,X2,...] = ndgrid(x)
```

is the same as `[X1,X2,...] = ndgrid(x,x,...)`

.

**Examples**

Evaluate the function

over the range .

**Remarks**

The `ndgrid`

function is like `meshgrid`

except that the order of the first two input arguments are switched. That is, the statement

Because of this, `ndgrid`

is better suited to multidimensional problems that aren't spatially based, while `meshgrid`

is better suited to problems in two- or three-dimensional Cartesian space.
