Re: Dynamic c++ question: operators

[Paul Kienzle]

Have you tried it?  It might already work.  

If it doesn't, then from what I can read from the tangle of preprocessor
macros in liboctave/mx-op-defs.h and src/ops.h, the following should work:

        boolMatrix c(mx_el_lt(a,b));
or
        bool mx_el_lt(a,b).any();
or
        bool mx_el_lt(a,b).all();

You could easily define:

        boolMatrix operater < (const Matrix& a, const Matrix& b)
        {
           return mx_el_lt(a,b);
        } 

Similarly for gt, ge, le, and, or
