plot 2 vectors not same length

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

griddedInterpolant works fine if you use it correctly, but you didn't show any code. Just saying 'it doesn't work' without saying why or showing what you tried is no use to anyone.

doc interp1

should work fine though anyway in this case.

Also, if you want people to answer your question try putting some useful tags. They are there for your sake so at least take the time to put something intelligent rather than '1'.

Hi Adam,

thank you for ur advice, i will keep it in my mind for the next questions. i tried this code bellow:

%zeit_est = time 

F = griddedInterpolant (412, zeit_est)

Im trying basically to to minimize the elements of vector time to 412.

but i keep getting this error

Error using griddedInterpolant Interpolation requires at least two sample points in each dimension.

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.
