MATLAB: How to find a vector in a matrix

Question

Hi all,

Assume a vector:

v = [1:3:1000];

How can I find the number of columns of each value in the vector:

   x = [100, 280, 781, 925, 997];

in the bigger vector, v.

I tried:

y = find(x == v)

But no success! Any hint is greatly appreciated 🙂

Answer 1

 [~,y]=ismember(v,x)
