I'm having a problem to reduce expression like this below:
R11a R11b + R11a R12b + R11b R12a + R12a R12b
---------------------------------------------
C1a C1b C2a C2b R11a R11b R12a R12b R2a R2b
I want use substitution:
R11a * R12a R11b * R12b
----------- =R1a; ------------ =R1b;
R11a + R12a R11b + R12b
so that I can get this expression:
1
-------------------------------
C1a C1b C2a C2b R1a R1b R2a R2b
Is it possible?
-Thank You

I guess you are trying to use symbolic variables. You can try with Matlab's Symbolic Math toolbox -> MuPad. It is a much better tool for symbolic calculus. The kind of operation you are trying to perform is not likely to be possible anyway.
