During the installation of ARM Clang compiler for STM32F4 discovery board, MATLAB showing an error of undefined variable.

[SChau.3]

Hello all,

I installed the "Embedded Coder Support Package for STMicroelectronics Discovery Boards" from the MATLAB (2018a) add ons. And followed their steps given in the user guide. But for the installation of "ArmClang Compiler", they have given one MATLAB command. So, I used that command in MATLAB command (matlabshared.toolchain.armclang.register) window it is showing an error - Undefined variable "matlabshared" or class "matlabshared.toolchain.armclang.register".

Please guide me.

Thank you.
