=========

Truthfully though, it would probably be better to build this by creating a subclass of the MATLAB double type, as down at the bottom. Then you could more easily inherit the other mathmetical operations +,-, etc...

ans =

0 0 1 0 2 Inf



%%%%%%%%%%%%%%%%%
classdef SpecialZeros<double

methods

function obj=SpecialZeros(data)
obj=obj(a)double(data);
end

function out=mrdivide(A,B)

C=A./B;
C( isnan(C)& A==0 )=0;
out=C;

end

function out=rdivide(A,B)

C=double(A)./double(B);
C( isnan(C)& A==0 )=0;
out=C;

end

end

end
