How do I obtain the nyquist plot of transfer function ((πe^(-0.25s)/s) in Matlab? What is the code to get nyquist plot of exponential functions?

You can use the nyquist or nyquistplot function in MATLAB to create a Nyquist plot of the frequency response.
You can use the following code to understand how to create Nyquist plot for your zero-pole-gain model
s = zpk('s');
G = pi * (exp(-0.25*s))/s;
grid on;
