Hi,
I'm trying to extract the imaginary part of an analytical expression, i don't find the appropriate function in OriginLab 7.5. I've tryied : 'cc.m_im' syntax as showed in a Help exemple, but it doesn't compile. How can I do it?

Thank you.

cc.m_im will work fine if cc is a single complex value. For example,

complex cc(3.45, 6.78);
out_complex("value = ", cc);
out_double("real = ", cc.m_re);
out_double("imag = ", cc.m_im);

Output...
value = 3.450000+6.780000i
real = 3.45
imag = 6.78

If cc is a dataset or vector you can either extract the imaginary value of a specific component...

int i = 0;
out_double("imag = ", cc[i].m_im);

or extract all imaginary values to a <double> vector...

vector vi;
cc.GetImaginary(vi);

Perhaps you should post the code you are trying to compile.
