Hi all,

i would like to plot 2 vecotrs not the same length ( velocity with 412 elements and time with 380169 elements), i tried this with the "griddedInterpolant command" but it doesnt work. I want that time-vector to have the same lenght as velocity-vector if that possbile. I will appreciate any help

The code you posted shows that you don't understand even basic MATLAB syntax. I recommend that you go through some of the many freely available online tutorials. This page is a good starting point.

"...[interpolate to] same length ( velocity with 412 elements and time with 380169 elements)"

Besides the other comments, you'll need the time corresponding to the velocity elements. Without, there's no way to know which to place where along the axis. One could assume (altho that's all it would be) that they're linearly-spaced with the first at point 1 and the last at the end of the time vector and just use the ordinal values but we have no way to know about that.
