A simple function of three variables

**Syntax**

**Description**

`flow`

, a function of three variables, is the speed profile of a submerged jet within a infinite tank. `flow`

is useful for demonstrating `slice`

, `interp3`

, and for generating scalar volume data.

```
v = flow
```

produces a 50-by-25-by-25 array.

```
v = flow(n)
```

produces a 2`n`

-by-`n`

-by-`n`

array.

```
v = flow(x,y,z)
```

evaluates the speed profile at the points `x`

, `y`

, and `z`

.

```
[x,y,z,v] = flow(...)
```

returns the coordinates as well as the volume data.
