I have to make a Nyquist Plot from frequency response data. I have the real and imaginary parts of receptance stored in separate matrices and I have frequencies stored in an another matrix. How do I plot the pairs of real and imaginary parts of receptance against frequencies in MATLAB?

As per my understanding, you are trying to make a nyquist plot from frequency response data.
You can determine a transfer function from your frequnecy response data using the “tfest” function from the System Identification Toolbox and then use the “nyquistplot” function in MATLAB to create Nyquist plot.
You can refer the following MATLAB documentation links on “nyquistplot” and “tfest” respectively for more details.
