In this example, we are going to solve a system of linear equations having two equations and three unknowns using thesolve()function. We obtain the solutionsxzandyzin terms of the z. The values ofxzandyzcould be changed according to the values of z. So, we can say this system obtains ...

Warning: Possibly spurious solutions. [solvelib::checkVectorSolutions] so consider using a numeric solver with different initial parameter guesses to look for other solutions, or (preferably) use the Global Optimization Toolbox functions to find the global minimum if there seem to be several local ...
Using what you suggest, I made the code below to learn about ODE15i considering a f(t,y,y')=0 problem. I'll let it here if One someday has the same question.res
I'm trying to solve a system onNnonlinear equations. For, for example, I can simply input 5 equations by hand that has 5 variables in total. Here's an example just to show what I use; %%%%% Example %%%%% f=@(x) [x(1)^2-x(2); ...

, choose solvers, and set options. Use the Optimize task to specify and solve constrained and unconstrained nonlinear programs, linear programs, quadratic programs, second-order cone programs, mixed-integer programs, linear and nonlinear least squares problems, and systems of nonlinear equations....
FSOLVE is telling you that an exact solution could not be found. However, because you had more equations than unknowns, it did default to a least squares algorithm. So, there was no real point to using lsqnonlin, except in my example to prove to...
