I beg your pardon, I got some unexpected result of plot number of line. I have uploaded the .mat files which contained the x,y axes data.
The code is as below:
title( ['Plot Bode']);
xlabel( 'x=Freq-axis (in 10^n)') , ylabel( 'y=data value-axis (in dB)' );
But I get 3 lines on the plot figure, as I expect to be only one. One is possible because of the hypot(), root of square , but there is another one (the lowest one) I thought it's very strange, its y-values seems same as reciprocal of x-values, Can anyone know why does it plot this ? And how to fix it ?
Thank you very much.
