1) Is there a way to compile octave code? (so it'll run faster then when 
  it is interpeted)
  3) Is it possible to call Octave functions (to inverse a matrix, 
  diagonalize etc) from a C program?
No, you can't compile .m files. You can, however, write a C/C++ program making
calls to octave library.

  2) Can one handle integers in Octave (in the interest of efficiency)
yes, you can; octave has several builtin types, and even a facility to
add custom types (but it requires extending octave library)

No.  But you can recode it into C++ and dynamically load it.

No.

See octave/src/DLD-FUNCTIONS/inv.cc (or maybe inverse.cc) for an 
example of how to write a C++ function which calls the liboctave 
function for inverse
