Defining integers in Matlab

Good evening,

I am in need to define a variable in Matlab as an integer, according to my text book, I have to insert a command that calls a function from Maple in Matlab, but when introducing the commands, I get the following error

Undefined function or variable 'maple'.

I have included a picture of my textbook that explains the procedure.

Am I missing any files or expansion pack? if so, where can I find it?

Thanks!

int() is not for declaring something to be an integer: it is for integrating a formula (calculus)

To use maple() you need to do one of the following:

• Use MATLAB R2007a or earlier, with the Extended Symbolic Toolbox -- this is what your textbook assumes you are doing; Or
• Install MATLAB R2007b or later, and then separately purchase and install Maple 11 or later (might require Maple 12, possibly); the Maple installer will (typically) detected that you have MATLAB installed and will give you an opportunity to install Maple as the MATLAB Symbolic interface; if it does not automatically detect MATLAB then there are ways to manually run the installer. The current Maple price for students is about $US100.

If you have MATLAB R2007b or later and MATLAB's Symbolic Toolbox, it is possible to call into the newer symbolic engine, MuPAD, to construct piecewise. I show how to do it at https://www.mathworks.com/matlabcentral/answers/325774-generating-piecewise-in-r2016a#answer_255400

If you have MATLAB R2016b or later an MATLAB's Symbolic Toolbox, there is now a direct call to create a piecewise function; see https://www.mathworks.com/help/symbolic/piecewise.html
