How to compare two vectors? [message #58856] Fri, 22 February 2008 04:24

Hi,

i have a the matrices

a = [0,2,5,8,9] and
b = [2,9].

Both are much longer in real life but still monotonously increasing.
What i want is a matrix c, containing the indices of a, where an element
of b is found in a. In this example it would be

c = [1,4].

Is it possible to do this with "where"?

Yann
