Follow-up Comment #8, bug #60784 (project octave):

"Basic mem." is the main memory occupied by the operating system and after
starting Octave.
"def. A" is the main memory usage after defining the Matrix A.
"det (A)" is the main memory usage while computing det(A). 
"det (double (A))" like above, only done for the "logical" case.

You can use a tool like htop and observe on a second terminal screen (not as
convenient as tic-toc).

The problem is, there are only "single" and "double" implementations
available.  Everything not "single" from the start gets eventually casted to
"double" under the hood.

This is what I mean by "no surprises".  The user has to decide which of the
two available LAPACK implementations "single" or "double" is suited for his
problem.
