Matlab says that the function is undefined after installing a toolbox

Hi, I'm using matlab r2018a with student license, and was trying to use the function 'num2bin' to convert decimal number into binary form

matlab said fixed point designer was needed to use the function so I installed it.

but after installing it now the program is telling me that the function is not defined.

I have no idea what this is about.

Can anyone help please?

Did you assure that the Fixed-Point Designer was added to the Matlab path?

Also, "installed" is not the same as "licensed"

One thing to do is

restoredefaultpath
rehash toolboxcache

Hey, please ensure that the installed toolbox to convert the base of the numbers is on the same path as in MATLAB. Without that, it might not work.
