Nice greeting,
could you please help me to figure out how could write a MATLAB code for dispersion curve of the surface wave?
Thanks
Hiba
Hiba,
So why Matlab is the choice if you are more familiar with other language? I would imagine any programming language can do the job once you know what you are doing.
For Matlab, do following links provide any help?

Where is the surface wave signal coming from? could you provide an example of wave data and one example of the kind of dispersion curve you would like to plot?
An easy way seems to go for 2D FFT, having arranged you data set in matrix form, with data in the columns and temporal data in the raws. Have a look at this:

and this:

dear Miguel,
thanks a lot for your assistance, the paper that you sent is similar to what I am looking for..........the surface wave signal coming from impact load on the surface, and the wave data is a time history for the two receivers on the surface due to that applied load (SASW) , so I want to write a MATLAB code for these two signals to get the dispersion curve for it ... to be honest I am new user for the MATLAB program......could you please find the atachment file (example of my time history data)
Thanks in advance
Hiba

Hello,
For plotting the dispersion curve VRayleigh = f (frequency), you have to acquire enough point measurement at different point at the distance d from the impact load. With this file calc01, you can read your data from Excel to Matlab
Dear Hiba al-adhami
does anybody know how to plot dispersion curve for composite materials for lamb wave analysis?
Hello,
See SFK transform is the enhanced method for f-k analysis of MASW data.
The matlab code with the SFK transform implementation (dispersion curves are plotted)
Code SFK-transform
it is very easy. You run an example: it draws the dispersion curves - you see how it works.
also you can get it on mathworks:
