MATLAB: Fsolve – function with two input arguments

fsolvefunction

Hello!
Is it possible to solve function with two input arguments? I have function in which I input two parameters and it returns one.
Example:
x = function(a,b)
x.JPG
But now i have a problem. I know parameters x and a, how do I get parameter b? Is it even possible?
Thanks for your reply!

Best Answer

function b = find_b(knownX, knownA, guessForB)
    fun = @(b) pfun2(knownA,b) - knownX;
    b = fzero(fun,guessForB);
end
Depending on your pfun2, you may or may not need a guessForB that is close to the right value.
