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
longer necessary. Use slice(v,xi,yi,zi) instead. 
> 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.
