problems using slice function

I have been having some problems using the slice function; I am using the following code;

```x = [-7:1:9]
y = [-7:1:9]
z = [-7:1:9]
```
```zslice = [0, 5, 9]
```
```v = my_ans (fft values calculated)
```
```slice(x,y,z,v,zslice)
```

The error message I am getting is as follows;

```Warning: Specifying the number of columns is no
> In slice at 55
Error using  /
Matrix dimensions must agree.
```
```Error in slice (line 57)
v =
reshape(v,size(v,1)/args{5},args{5},size(v,2));
```

Any ideas what the problem is??

Many thanks

:)

The only way that slice() takes 5 arguments is if the last argument is a string indicating the interpolation method.

There are four-argument versions of slice() in which V is the first argument, but those only have one z.

There are seven-argument versions of slice() in which x, y, z, and v are the first four arguments, but the last three arguments must be xi, yi, zi. You seem to have left out the xi and yi.
