Solving Equations
The Symbolic Toolbox can be used to find solutions for single or simultaneous equations using the solve command.
Solving a Single Equation
The first task is to solve a single equation for the variable , with the result stored in the variable a. This can be done with command solve.
a = solve(f,x)
|
> Exercise: Using solve for a Single Equation > Go through and type in the code for the following steps to solve the single equation.
> Watch out! There is an error that you will need to correct!! |
|
| 1. Decide what is (you will need to rearrange the equation) |
In this case
|
| 2. Create a symbolic variable | syms x |
| 3. Create a symbolic variable by assigning a symbolic expression to it | f=10/(x^3+1)-4+2x |
| 4. Solve | u = solve(f,x) |
