# Rearranging Symbolic Expression With ‘horner()’ Command In MatLab®

Mathematical rearrangements are very important to obtain monitorable functions. These kinds of rearrangements require hand calculations generally. But, Matlab® provides various kinds of useful tools to do them in the command window. You can do these kinds of mathematical rearrangements with the ‘horner()’ command.

## How To Use ‘horner()’ Command In MatLab®?

``````>> syms x
y = x^4-6*x^3+12*x;
horner(y)

ans =

x*(x^2*(x - 6) + 12)

>> ``````

As you see in the example above, we created a symbolic variable ‘x’ with the syms command. Then, we created an equation.

Consider a situation that we want to rearrange this inside ‘x’ joint brackets.

We just typed ‘y’ inside the Matlab® command window to obtain the joint brackets of ‘y’. Take a look at the answer above.

## Conclusion

The use of the ‘horner()’ command in MatLab® is very simple as you see above. You can use the ‘horner()’ command instantly whenever you need it.
