You need to save data using a Scope block, ensuring that the data is formatted as a "Structure with Time". Search this documentation page for "History pane" and you'll see how to do this.

Once you've run this model and the scope data gets saved to the workspace, you should see it in the powergui block's FFT tool. You can then follow the steps as shown here.

dear sir,

actually my program is written in .m file (script file). how sir, i display it in scope?

i have variable which stores values of voltages with harmonics like

optimumv = 92.1596 -1.3810 -1.1094 2.7546 -0.2628

1st=92.1596 
5th harmonic=-1.3810 
7th harmonic=-1.1094 
11th harmonic=2.7546 
13th harmonic=-0.2628

i want to apply fft on above data. is this possible sir, i want a view of output as attached?

Hi Sebastian Castro, i've seem your blog, and that's why i ask you for help, because you also work with phisycal modelling, please refer to this link to understand my doubts about SPS, http://es.mathworks.com/matlabcentral/answers/315484-is-it-possible-a-buck-converter-in-discrete-time-not-in-continuos-solver
