You don't have difference but I do (only in  your matrix create)

2.1.50  matrix create       5.702     100.000       0.057
2.1.57  matrix create       5.620     100.000       0.056
2.1.61  matrix create       8.653     100.000       0.087

I don't know why rand in my 2.1.61 is 1.5x slower (all version use
some octave-forge, 2.1.61 has recent (about 7 days) from cvs)

But my real (deterministic) application is going to infinity :(

2.1.50  68.4  seconds
2.1.57 179.37
2.1.61 261.90

My application is (badly) complicated - above 180 m-files.
Today I will finish my code instrumentation to find drawbacks.

Another issue with my code is that results from 2.1.50 are different to
2.1.57/2.1.61 (some rounding problem???).
