No. Octave's precision is defined by your CPU's implementation of
double precision, i.e. it's defined by your hardware. It can't be
changed in software.

The vpa function from the symbolic package is very limited and nearly
useless. The symbolic package for example doesn't work with matrices.

I recommend you use another program. I know in Maxima you can set the
fprec variable to use variable-precision for floating point
arithmetic.
