Getting "Execution of script roots as a function is not supported:" error

Hi,

I am trying to find the roots of an equation x = x^3 + 4*x^2 - 8* x -12

Below is my script:

x = [1,4,-8,-12];

y = roots(x)

I have saved this code in flie_3.m script and numming it and its giving me error as

"Execution of script roots as a function is not supported:"

It seems you have another roots.m file which is different from MATLAB's built-in roots function.

Please check the following command

which roots -all

You will get custom roots.m (in bold) and built-in roots.m files.

<SOME_PATH>\roots.m

<MATLAB_ROOT>\toolbox\parallel\gpu\@gpuArray\roots.m % gpuArray method

<MATLAB_ROOT>\toolbox\matlab\polyfun\roots.m % Shadowed

Rename the custom roots.m file to such as myRoots.m.
