S-Function Builder - Integer and decimal part

I am using S-Function Builder and I am trying to extract the integer and the decimal part of an inserted signal by using the modf function like that:

• *ref_decimal_up = modf(*ref_up, &*ref_integer_up);

It seems that this method doesn't work. I have tried also this:

• int* ref_integer_up = (int*)ref_up;
• double* ref_decimal_up = *ref_up - *ref_integer_up;

Unfortunately that doesn't work either. Do you have any idea?

Thank you in advance!

Hi,

This couldn't be executed in MATLAB as it contains a reference pointer (*) operator, which isn't supported in MATLAB syntax.

Hope this helps.
