Solve systems of nonlinear equations in serial or parallel. Find a solution to a multivariable nonlinear equation F(x) = 0.You can also solve a scalar equation or linear system of equations, or a system represented by F(x) = G(x) in the problem-based approach (equivalent to F(x) – G(x) = 0 in the solver-based approach).

01.02.2017 · What are you solving for here? You have two equations; I'll assume two unknowns (x, y). You need more basic information before you can use a tool like Matlab. It might encapsulate a lot of the details for you, but it won't make algorithm choices for you. You still have to know something, especially about your system of equations.

The solve function returns a structure when you specify a single output argument and multiple outputs exist. Solve a system of equations to return the solutions in a structure array. syms u v eqns = [2*u + v == 0, u - v == 1]; S = solve (eqns, [u v]) S = struct with fields: u: 1/3 v: -2/3.

28.09.2020 · Here is the rub - you are in trouble IF you really want to find ALL solutions of a system of totally general nonlinear equations, regardless of the domain. First, any problem can have infinitely many solutions, even in a finite interval. Consider sin (1/x), for example, with infinitely many roots in any finite interval that contains zero.

Feb 02, 2017 · I need to know how to solve a system of nonlinear equations but varying a parameter, so that every time you change that parameter will throw me the result of that system (need all results), I thought a for, which is changing the parameter, solve the equation and each result is stored in a spreadsheet, the problem is that as you can not solve ...

Nov 26, 2013 · I have (on paper) determined that my nonlinear equation is as follow: 2*sqrt (P)* ( (x)^1.5) + .10905*x- 0.0363 = 0. where P is a pressure and x happens to be a molecular concentration in this case. So, I can solve the above equation for set values of P using the following function file (when P = 1). function [x,P] = myfun (x)
