I think something like the following should work.

  Matrix m1 = ...;

  m1.apply (xround);  // Changes values in m1.

  Matrix m2 = (xround);  // Creates new matrix m2 with rounded vaues.

The xround function is declared/defined in lo-mappers.{h,cc}.


Thanks. Looping at the matrix class, I saw the map "method" (or whatever the correct term is). I was suspecting that it could be used. If I get it to work I'll add it to the quick reference.
