hi. i have raw velocity data. i need to get the local maxima of that data in velocity vs time plot.findpeaks() needs a liscense, so is there any other function similar to findpeaks?

There are plenty of peak finding variants in the File Exchange for free. I can't vouch for the quality of any of them, but you can evaluate them for your usage.

Please use function diff.
for example:
a = rand(15,1);
t = diff(a);
lo = t > 0;
ii = strfind(lo(:)',[1,0]) + 1;
plot(a(:));
hold on
plot(ii(:),a(ii),'ro');
