Jul 23, 2018 · How can I solve the following equation using Matlab, 6.84e24X^1.8164+9.95E13*X+1=0, Could you please help with syntax?

This tutorial helps you use MATLAB to solve nonlinear algebraic equations of single or multiple variables. In order to use the MATLAB solvers, you must first be able to write MATLAB functions. There are two different methods to create a function - (a) inline command, and (b) Matlab editor.

Dec 27, 2023 · As a fellow engineer, I know how tricky solving those types of interdependent equations can get. But have no fear – MATLAB‘s fsolve() function is here! Let‘s explore how this numerical solver can reliably help find the intersection points even for complex nonlinear relationships between variables.

Jan 16, 2023 · Solve a nonlinear function with one variable. Learn more about non-linear function, one variable Hi, I need to solve this function using Matlab in single script: x - x^2 + 2*{sin(x)*(x-1)} = 0 Would you be able to provide a sample code and method to do this in Matlab?

Sep 30, 2022 · I would like to solve a system of non-linear equations in Matlab with fsolve, but I also have to differentiate the functions with respect to two variables. Here is the problem in steps: Step 1: I define the system of non-linear functions F:

Nov 21, 2019 · Now if you examine solF.parameters and solF.conditions you will see that there are 16 sets of solutions for each variable, with the sets being defined in terms of three arbitrary integer variables, and each of the sets is defined in terms of a value being any of the three roots of a cubic equation. 16 basic forms, 3 solutions each = 48 basic sol...

S = solve(eqn,var) solves the symbolic equation eqn for the variable var. If you do not specify var, the symvar function determines the variable to solve for. For example, solve(x + 1 == 2, x) solves the equation x + 1 = 2 for x. S = solve(eqn,var,Name=Value) uses additional options specified by one or more Name=Value arguments.

Jan 12, 2023 · Learn more about nonlinear eqn solve, only one variable MATLAB.

Jul 15, 2013 · If solve doesn't work out, as far as finding complex roots of nonlinear equations goes, there's not much directly built into Matlab as far as I know. You'll need to break the problems into real and imaginary parts and use fsolve or a least squares solver.

Mar 12, 2012 · In some places in your equation, you use sqrt (), but in other places you use ^0.5 . The two are not equivalent in algebra. In algebra, it is not known whether the 0.5 is the representation of 1/2 or of 5/10 or of 10/20 and so on -- interpretations that can affect the sign of the result and can affect which complex root is chosen.
