Matrix with continuous variables

I have three variables: mu1, mu2 and mu3 which all indicate a workers speed.

I randomly assume here that mu3 = 1. Mu1 and Mu2 can both vary between 0 and 2 with steps of 0.001.

This gives me ratios of p1=mu1/mu3 and p2=mu2/mu3.

I have probabilities for states that are indicated with Pi1 to Pi10 (I worked with Markov chains) which means I have a 10x10 Matrix.

How can I get Pi1=..., Pi2=..., expressed in a mutual variable and p1 and/or p2 by using Matlab? I know how to solve simple matrices but since I'm using p1 and p2, I keep receiving errors and I do not know how to proceed.

Thank you in advance!
