Hi everybody!
I am using the routine rs_test.pro (idl library). I have two data set,
the first one is a 105 elements array (x), while the second one is a
103 elements array(y).
I read the data, but when I use rs_test.pro the routine returns
%Unable to concatenate variables because the dimensions do not agree:
Y
% Error occurred at: RS_TEST 96
% $MAIN$
% Execution halted at: $MAIN$
Why? Where is the problem and it is possible to solve it?
Thank a lot!
Cheers
Steve

Hello,
For RS_TEST the X and Y arguments must be *vectors*. Since your X and
Y have two dimensions the don't qualify. It's a subtle problem and it
drives some programmers crazy - while other's delight in it. You can
fix the problem by using REFORM do removed the 'degenerate' dimension.
vecX = REFORM(x)
vecY = REFORM(y)
result = RS_TEST(vecX, vecY, ...)
