Chandrasekar Sureshkumar am 3 Sep. Stimme abgeben 0. Abbrechen In Zwischenablage kopieren. Hi, I've been trying to solve a set of nonlinear equations in many variables. I see that multiple solutions exist for these and fsolve does not output all of them.

For real-valued functions, the norm squared can be substituted, f x -b. For optimset , the name is JacobMult. Display Level of display. Your equations have more than one root or set of roots. These parameters are used only by the large-scale algorithm: JacobMult. So, for example, it could take a backward, rather than a forward, difference to avoid evaluating at a point outside bounds. Can anyone explain to me what is going on here or at least some of the possible reasons if it isn't possible to say exactly why? Translated by. Large-Scale Algorithm Only.

Description fsolve finds a root zero of a system of nonlinear equations.

Some options apply to all algorithms, and others are relevant for particular algorithms. The algorithm is a variant of the Powell dogleg method described in [8]. Create a problem structure for fsolve and solve the problem. Describes the exit condition:. By default fsolve chooses the trust-region dogleg algorithm. You can use fzero. Termination tolerance on the function value, a positive scalar. You will get the equation as mentioned in this answer. Y is a matrix that has the same number of rows as there are dimensions in the problem. Saunok Chakrabarty am 5 Nov.
