A switch case with multiple results or switch expressions?

Is such a switch case possible? If not, whats my workaround for it?

  switch r,d
    case d=1 && r=1
        continue
    case d=1 && r>1
        disp('zero')
    case d=0 && r=1
        disp('positive one')
    case d=0 && r>1
        disp('other value')
    end

First we need to fix some syntax issues.

• A CONTINUE may only be used within a FOR or WHILE loop
• Logical comparison requires 2 equals: d==1 && r>1

One way to swtich based on the value of multiple variables is this:

r = 1;
d = 0;
switch true
    case d==1 && r>1
        disp('zero')
    case d==0 && r==1
        disp('positive one')
    case d==0 && r>1
        disp('other value')
end

positive one

It is true that a continue can only be used within for or while, but we could speculate that this switch logic is indeed inside a loop.

  switch true
    case d==1 && r==1
        continue
    case d==1 && r>1
        disp('zero')
    case d==0 && r==1
        disp('positive one')
    case d==0 && r>1
        disp('other value')
    otherwise
          disp('Uh-oh!')
    end
