I have a nx3 matrix. I need to find row index if i know all the column entries of a particular row. How to do it in a simple command.

Thanks,

Amit.

If A is your array, for example

A=ceil(10*rand(10000,3))

and you want to find [1,2,3] this command

find(ismember(A,[1 2 3],'rows'))

will return the row index(es) of matched data.
