How to equate data from two arrays?

Hi,

Say I had two arrays A and B which are not of same length. The array data in A is also present within the array data in B but B also has other data that are not relevant. I want to find the data of A in B and return the indexes of these data in B. Is there a way of extracting this?

Thanks

'ismember' is what you need.
