I'm trying to use the trapz command on MatLab R2015b.
I have 2 waves of data : y1(1x1036 double) and y2(1x9958 double) with different acquisition time, and I want to compare the area under both curves. But since the second wave have way more points I found a value much higher that did not make sense.
How can I do to tell the trapz function to take one value out of 10 for exemple? I've tried messing with the X parameter in
but I did not manage to make it work.
