It is more than "probably".  Cleve Moler has already stated publicly in

http://www.mathworks.com/company/newsletter/clevescorner/winter2000.cleve.shtml

  Regrettably, one popular MATLAB feature must be a casualty with the
  introduction of LAPACK. The flops function, which keeps a running count
  of the number of floating-point operations, is no longer feasible. Most
  of the floating point operations are now done in optimized BLAS that
  do not keep flop counts. However, with modern computer architectures,
  floating-point operations are no longer the dominant factor in execution
  speed. Memory references and cache usage are most important.

Octave leads, Matlab follows :-)
