taking modulus

hello

i require to take the modulus of a particular result..

the command in the help window gives the mod of the remainder,...
example
AM = a1(1,2) / ( a1(1,1)*r)
here, a1 matrix and r are already defined.

i require the modulus of AM for further calculations..
that is.. i want to take the positive value even if the result if
negative.

plz help

There is a function 'mod' which will give you a non-negative result if
your divisor is positive.  That is, mod(8,5) = 3, mod(-8,5) = 2.  What do
you plan to use as the divisor - is it the denominator above, a1(1,1)*r?
If so, you need that to always be positive.
