Finding corresponding values between vectors

umps_land is a vector and a subset of vector umps. The subset was selected graphically using the brush. vmps is a vector the same size as umps. I want to (non-graphically) find the values of vmps that correspond to umps_land and call it vmps_land. How do I accomplish this seemingly easy operation? (and why can't I find documentation on this??)

Try ismember

index = ismember(umps,umps_land);
vmps_land = vmps(index);

Thanks, Rong Yu. That seems to have worked!

@Rong Yu, in the future post your answer as an answer rather than a comment to the question. That way the OP can accept your answer and you get reputation.

Thank you, Guillaume! I put my suggestion into the answer.

Try ismember

index = ismember(umps,umps_land);
vmps_land = vmps(index);
