Yes, that is the general usage of N-D array in Octave documentation.
As far as I am aware, the Mass matrix must be a 2-D full or
sparse matrix.
Okay. Is the matrix also required to be real and square?
Thanks,

The
ode solver options "Mass" and "Jacobian" can be either a
function
handle or a matrix according to odeset(). If it is a matrix,
does that
mean a numeric 2-D matrix or just a numeric N-D array?
The input validation for ode15i and ode15s has to be re-done
because of a
change in the behavior of str2func, and I'm taking the
opportunity to
improve it.
Thanks,
