Hello Everyone. This is my first post.
I have 3 equations that I am trying to solve for 3 unknowns.
I tried using the MNEWT.DEM file with modifications but I do not understand how to set the alpha matrix with my equations.
I have these 3 equations:
func = Y * (-0.045045^ (1 / X)) + Z - 10
func = Y * (-0.303034^ (1 / X)) + Z - 20
func = Y * (-1^ (1 / X)) + Z - 50
Best I can guess is the alpha matrix units are a negative differential of the corresponding sub-equation. And I can see this easily from the sample file. I've tried to plug my differentials into the alpha matrix with no luck. I think it's because the structure of my equation is more complex than the sample equations.
Can anyone please advise as to how I can obtain the proper alpha matrix and solve for these 3 unknowns?
Else, is there a better way to solve the set of unknowns in a different method?
Your help is very much appreciated.
