How can I add an absolute value to an optimization expression I am trying to optimize? MATLAB shows the following error :
Undefined function 'abs' for input arguments of type 'optim.problemdef.OptimizationExpression'.
problem is :
minimize abs ( ax + by + cz - d )
subject to , x,y,z are integers in some range

Square it instead so as to not introduce a discontinuity
