comment:
- !ruby/struct:SM::Flow::P
body: The <tt>Matrix</tt> class represents a mathematical matrix, and provides methods for creating special-case matrices (zero, identity, diagonal, singular, vector), operating on them arithmetically and algebraically, and determining their mathematical properties (trace, rank, inverse, determinant).
- !ruby/struct:SM::Flow::P
body: Note that although matrices should theoretically be rectangular, this is not enforced by the class.
- !ruby/struct:SM::Flow::P
body: Also note that the determinant of integer matrices may be incorrectly calculated unless you also <tt>require 'mathn'</tt>. This may be fixed in the future.
