How to get waveform from the given magnitude and phase?

I want to get the waveform from the given magnitude & phase or in the complex form in simulation. Please anyone give me solution for this.

Square wave?

sine wave from it's magnitude and phase in simulation

what do you mean by in simulation?

I think you need to try to explain your question in more detail. It's not really clear what you're trying to do, nor what you're having a problem with.

i need to get the fundamental component extraction from unbalanced load currents. But my source voltages are inform of wave forms( means i may get magnitude from it but i'm not getting phase of waveform) but the calculation for extraction calculations are in polar and exponential form .

simulation means in modelling but not in coding
