Check if a number is complex with MEX.

Hi!

I would like to test if a number is complex. With Matlab I can do that using the function imag

imag(x)!=0 .

How can I do that using a mex file?

Thank you very much.

Though it is late adding for future reference,

Yes we can verify by using "mxIsComplex(<pointer>)".
