fortran random number generator

[mikibelavista]

I am translating some code form matlab to fortran90,I need to generate random numbers for matrix.
This is how MATLAB code looks like,and gives me the same values all the time.
rand('state',0)
v = 2*(ones(c,1)*aa).*(rand(c,n)-0.5) + ones(c,1)*mm;
Is there any idea how to solve this in FORTRAN?

There are basically two routines: RANDOM_SEED and RANDOM_NUMBER. RANDOM_SEED sets the seed so you can get the same sequence every time. RANDOM_NUMBER generates the number. There are lots of examples of how to use them on the net.
