I am looking for a solution to the problem:
ag_p*Gamma_p - Sa = 0 with Gamma_p = A+B*ag_p.
A, B and Sa are constants.
This can be solved by performing iterations starting with a certain guess value for ag_p.
Note: I have solved it through FZERO function as given below. I am interested to iteratively solve the equation by assigning a guess value to ag_p, let's say from [0...inf], which updates Gamma_p and the iterations are performed until the solution is found ( Something similar to Solve Block in MathCAD). I need to have a numerical value for Gamma_p in each iteration because I will be comparing its value with another constant parameter to define some "if" conditions.
Sa = 2.7956;
A = 2.24;
B = 0.5547;
Gamma_p = @(ag_p) A+B*ag_p;
f = @(ag_p) ag_p*Gamma_p(ag_p) - Sa;
z = fzero(@(ag_p) f(ag_p), 1E-3)
