Question: fsolve - 4 equations - 4 Unknowns


Dear Maple Users

I am looking for specific answer, please see the following code,

by trial and error I estimated proper values for 4 parameters, and corresponding equations become close to zero.

However I need to make it automatically via maple, what can I do?

If I give ranges for parameters, there is no answer existed.

Thank you.
