How can I sum two plots that don´t have the same number of elements?

1 次查看(过去 30 天)
I have the following case which represents the pressure distribution over a profile:
I want to separate the intrados and extrados sections and calculate the sum of it. I´ve divided my data but the 2 parts don´t have the same number of elements. For example, I have 170 data points for the entire plot and 94 of them are data from intrados and the rest is extrados.
I can divide it and represent it:
but I have troubles with performing the sum. I need to create extra points somehow so the 2 data sets have the same number, how can I do it?

I think one of the methods is to perform data interpolation using interp1 so that both curves are interpolated at the same point coordinates.

Oh, that´s actually more useful. Will probably need to solve more cases so the automatic detection and separation on intrados/extrados will accelerate things a lot. Will try to implement it now. Thanks a lot!
