detect complex number in matrix

[Ken]

Is there some function that can tell me if a matrix contains any
complex numbers? Right now I loop through every matrix element and
test its type. Is there a better way?

I don't think there's a better way.

I don't think there's a better way.

Maybe we single type matrices could help (force_type=mpf should do the job).

But I also would just use any(type(x) is mpc for x in mymatrix).
