I'm not getting how to draw a DFT using coefficient.

c3 = 0.0880 + 0.1215i
these are the coefficients.

Hi,
From my understanding you have a set of complex coefficients which you want to plot. You can plot the magnitude response by calculating the magnitude of each complex coefficient using the function 'abs'. Similarily , the phase response can be calculated by using the function 'angle'.

Sir, basically I have a curve and by using no of co ordinates, I need to redraw that curve by Fourier series. Please tell me how can I do it.
