Undefined function 'rr' for input arguments of type 'double'.

Hi I am trying to use my MathLab 2012a and everytime I use rr( ) function, it keeps showing "Undefined function 'rr' for input arguments of type 'double' ". How can I fix this problem? the function rref( ) works but not rr( ). Please help!

What is rr? make sure that rr.m is in your current folder

rr is for the row reduction routine acting on matrix inside of the bracket.. how can I put rr.m in my folder?

Could you point us to a reference page for it? There is no rr() in current MATLAB, just rref
