I want to plot I (inphase) vs Q (quadrature) graph using 128*256 complex dataset. The dataset is attached(M2.mat). What is the shape of the graph? Please share the code.

how do you want the komplex data be displayed? You need four dimensions to plot a 2d matrix of complex and therefor 2d numbers

As per my understanding you want to plot I and Q from the complex signal mentioned in M2.mat.
Following piece of code will help to achieve it.
load M2.mat; %load the M2 file to the workspace
I = real(M2);
Q = imag(M2);
figure; hAxes = gca;
plot( hAxes, I );
hold( hAxes, 'on' );
plot( hAxes, Q, '--' );
Hope this helps
