In the text quoted below, I am rather satisfied with myself for being
able to trace through the code except for one bit. At what point in
the code does the parser translate "A\b" into xdiv and relatives?
look in src/OPERATORS/op-m-m.cc that defines the binary operator ldiv as
DEFBINOP (ldiv, matrix, matrix)
{
CAST_BINOP_ARGS (const octave_matrix&, const octave_matrix&);
MatrixType typ = v1.matrix_type ();
Matrix ret = xleftdiv (v1.matrix_value (), v2.matrix_value (), typ);
v1.matrix_type (typ);
return ret;
}
you'll find the code that calls this on src/ov.cc in do_binary_op that
is called in a number of different fashions elsewhere in ov.cc
