Enter output data, at the entrance of the same process.

Good Morning.

I await your help with much gratitude.

Through certain operations I get a matrix of 10 X 20 I call that matrix "arrmat"

Subsequently the values of "arrmat" I pass through several operations and I get another matrix of 10 x 20 and that matrix I call "rxx"

How do I enter the values obtained in "rxx" to the matrix "arrmat" and so on, cyclically?

Hoping you can help me. First of all, Thanks.
