I am a novice in learning MATLAB. I had this problem. I need to solve four equations using only one predefined function, fsolve. But my code can't print the result. It shows that the value assigned to 'x' in line 23 may not be used.

5 FSOLVE The MATLAB routine fsolve is used to solve sets of nonlinear algebraic equations using a quasi-Newton method. The user must supply a routine to evaluate the function vector. Consider the following system of nonlinear equations, and solve for x1 and x2: The m-file used to solve the above problem using fsolve is:

MATLAB: How to use Fsolve with multiple variables. fsolvefunction handlevariables. Hi. I am trying to solve two non-linear equations using fsolve.

x = fsolve(fun,x0) starts at x0 and tries to solve the equations described in fun. x = fsolve(fun,x0,options) minimizes with the optimization parameters specified in the structure options. Use optimset to set these parameters. x = fsolve(fun,x0,options,P1,P2,...) passes the problem-dependent parameters P1, P2, etc., directly to the function fun.

23.02.2014 · %I have 3 nonlinear equation. I need to find unknowns I tried fsolve function but I couldn't use it properly, could anyone explain for me how can I use fsolve function?

fsolve finds a root (zero) of a system of nonlinear equations. x = fsolve(fun,x0) starts at x0 and tries to solve the equations described in fun. x = fsolve(fun,x0,options) minimizes with the optimization parameters specified in the structure options. Use optimset to set these parameters.

fsolve supports code generation using either the codegen (MATLAB Coder) function or the MATLAB Coder™ app. You must have a MATLAB Coder license to generate code. The target hardware must support standard double-precision floating-point computations. You cannot generate code for single-precision or fixed-point computations.

c = -2; fun = @ (x)paramfun (x,c); % fun now has the new c value x = fsolve (fun,x0) Equation solved. fsolve completed because the vector of function values is near zero as measured by the value of the function tolerance, and the problem appears regular as measured by the gradient. x = 1×2 0.1788 0.3418.
