In a writable folder, create a System object,AddOne, which subclasses frommatlab.System. Save the code asAddOne.m.

classdefAddOne < matlab.System% ADDONE Compute an output value that increments the input by onemethods(Access=protected)% stepImpl method is called by the step methodfunctiony = stepImpl(~,x) y = x+1;endendend

Write a function that uses this System object.

functiony = testAddOne(x)%#codegenp = AddOne(); y = p.step(x);end

Generate a MEX function for this code.

codegen-reporttestAddOne-args{0}

The-reportoption instructscodegento generate a code generation report, even if no errors or warnings occur. The-argsoption specifies that thetestAddOnefunction takes one scalar double input.
