Hi,

Please see the enclosed file.

Three equations you can solve only three variables, the solve block needs to know the rest.

Solve block needs three guess values for the three unknowns

You now need to define the functions K', k',r',

You need to define the variables a,b,S,T, ,z even if parametizing the solve block

OP when used as a function outside the solve block will produce a column vector of three elements Q',s',t'

See how you go defining the functions and variables needed above the solve block. Get back to the forum if you have more problems.

Cheers

Terry
