Hello,
i've got 8 symbolic expressions and i want to simplify this system of equations together. So i've there identical expressions in 2 or more equations the number of mathematical computations can be reduced.
It is a symbolic problem using the symbolic toolbox.

What would you do with the simplifed system? Solve it for the parameters?

If you use matlabFunction and request that it be written to a file, then the default is to optimize. The optimization step involves searching for common subexpressions and assigning them to variables and reusing the variables.
The end result is a .m file that is intended for numeric calculation.
Caution: not very long ago, optimization was badly broken, so test before trusting.

I haven't tested over the last couple of releases, but not very long ago, the optimization phase had a series of problems for a number of years. It was completely unusuable for longer expressions.
