Hello everybody!

i need help extracting some values from a vector. More specifically, I have two vectors A and B (vector A contains 1: 3000 while vector B contains 10 random numbers) and I need to extract from vector A only the values contained in Vector B. I have already tried with "== "and" iseq ", but the vectors are not the same length and therefore I cannot perform the operation.

thank you for your time!

在 MATLAB Online 中打开

[intersection, indices] = intersect(A,B)

There you get the intersecting values and the indices to the intersecting values in A
