solve a non-linear equation for a 2d array values

Hello,

I would be grateful if you help me out in this issue. I'm a beginner in matlab and having a sigmoid function need to be solved for X:

Y = A+B-(B^(1-D)+C*X*(D-1))^(1/(1-D))

A,B,C, and D are the function cofficients, and Y is provided in 2D array. I need a script that returns X in 2D array.

Thank you

You can generally solve all non linear equation using fsolve function. What you need to do is convert the equation to explicit form and use fsolve to the solve the function.

I hope this gives you a headstart to explore more. There are other function also. Start with fsolve and then explore more.

Cheers.
