**Solving 3 unknowns from 50 Nonlinear equation MATLAB**

An initial guess is a guess, so it's always at least partly a matter of guess-work, not science. Often, the physical nature of the problem might suggest a good initial guess.... To check that, use 3 equations and solve them. 3eqn 3unknown can be solved. And substitute those to check if it satisfies the 4th. Only and only if satisfies 4th equation, the values are defined or else it â€¦

## How To Solve 3 Equation With 3 Unknowns Matlabb

### 2013-03-24Â Â· Hello, I have never really used MATLAB before, and I was assigned some homework on it. While I was able to solve most of them, I was unable to solve this one in particular, even after searching the internet and documentation, there was many kinds that I was left confused. Does anyone know the syntax for this general case: ax+by

- I have a set of three unknowns which I need to resolve from 50 different non linear equation. Which method should I use in matlab? I found out that fsolve can do that, but then I faced another issue.
- Hi Jason, there seems to be something funny about these equations. If you eliminate V from the first two, you can show that Re*sqrt(f) = constant.
- To solve a system of linear equations you can use linsolve(). You might need the symbolic math toolbox. You might need the symbolic math toolbox. 1 Recommendation
- where A is the matrix of coefficients for the equations and x is the set of unknowns, i could find the unknowns by: x=A\b
