| Nov 22, 2014 at 11:18 | comment | added | user11810 | Can you please let me know the method you followed to solve this issue? I am stuck on how to transform the psuedo frequencies to the actual ones to get the graph correctly. | |

I put a little code at the end of mfile. and got the same plot as right hand side of the mentioned plot. cof2=abs(coefs).^2; cof2trans=cof2'; maxmods=max(cof2trans); figure; plot(maxmods,freq) axis([0 60 0 1]) Best regards | |

| Jul 30, 2013 at 20:03 | comment | added | SAH | -@user4619 It's not Freq vs time, The time range is 0-20 and the frequency range is 0-2.5 but the right hand side plot is freq vs magnitude. I am not sure its exactly coefs or magnitude but obviously its proportional to cofes or cofes^2. tnx | |
| Jul 30, 2013 at 19:55 | comment | added | Tarin Ziyaee | @Electricman The plot on the right hand side is simply one column of your Frequency VS Time matrix. | |
| Jul 30, 2013 at 19:45 | comment | added | SAH | Thanks for modifying the code. But I didn't get an answer for my question yet.The question is How can I plot Freq-magnitude or scales-magnitude[no difference]. I want a plot like the right side of first picture.[it's in question]. thanks in advance | |
