Here, we show you how to rearrange mathematical expressions with the ‘horner()’ command in Matlab® with very basic examples below.

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

>> syms x
y = x^4-6*x^3+12*x;
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. 


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.
