Solve Nonlinear Equations with MATLAB

MATLAB solves nonlinear equations either symbolically or numerically with solvers such as "fsolve". This example demonstrates how to obtain a solution to sets of nonlinear equations.

as a beginer in MATLAB, your lectures are very helpful, short and very compact. keep it up !
thank you

Man I love you, I tried to solve some combustion equations using solve but got error then I tried your method with fsolve and worked❤️❤️

[davidtorres]

Thank you men, you save me. Very useful video!!!

i wanted to solve 2 coupled nonlinear equations but i'm getting "equation solved, solver stalled". could you help me out?

How to solve a system of 10 nonlinear equation with 10 variables, having parameters that must be calculated by another function and imported?

[Reyarth]

I need to solve a system of parametric non linear equations. How can I do that?
Thanks!

[muhammadaaqibrabbani]

Sir could it solve for an unkown constant like c instead of 9?

[enriquenieto]

Thank you !!! Well and simply explained

Hello, is it possible to add the constraints on z(1) and z(2) (or x & y ) in fsolve similarly to what you did in the solve function ?

[saddamhussainsoomro]

sir can you help me to solve 12 non linear equations with 12 variables, or guide anything please. Thanks

[danielcachafeiro]

Shouldnt you get as many roots as grades the polynomials are?

How to solve a system of non linear equations with different constant values that is read from a Csv file

[hojoduurenbileg]

Could you explain why you don't give the Myfunctions function any arguments when you put it into the fsolve.

Do I have to write that x is greater than zeor

[WytseZ]

Thanks for the explanation, very clear!
Possible improvement for your video; Use some de-essing software because it is very painful to listen now

how to solve the root 2 with 4 iteration and the starting point is also define?

[SaqrThabet]

that was an impeccable lesson, but [x, y]=solve([x^2+y^2 = = 20, y = = x^2], x>0, y>0, [x, y]) did not work properly with me. However [x, y]=solve('x^2+y^2=20', 'y=x^2', , 'x>0', 'y>0' ) did work just fine.

[khaoulabriki]

Thank you it is very helpful . if you can make a video to solve a nonlinear boundary equation ex:q = x''[t] + x'[t] + x[t] + x[t]^3;

[pamirkldis]

thanks a lot, you are the best <33
