PDIST does not accept complex data for built-in distances

I got an error beside this line of code:

done=pdist([a;a1],'minkowski')>=m;

where a and a1 are two matrices of the same size.

The error was:

Error using pdist (line 144)
PDIST does not accept complex data for built-in distances.

What does that mean? How can I solve this issue?

Thanks.

pdist() does not accept complex-valued data for the distance functions that are not user-defined.

You can define your own distance function to handle complex-valued data.
