Why I can't use function syms in MATLAB_R2016a and I can't even find syms in the help document?

[Walter Roberson]

syms is part of the Symbolic Toolbox, which is not part of basic MATLAB.

The Symbolic Toolbox is included with the Student Suite, but not in the unbundled Student license or any of the other licenses.

Also, even if the Symbolic Toolbox is included in your license, you would need to tell the installer that you wanted to install it.
