sdynpy.core.sdynpy_system

Defines a system of matrices representing a structure.

The System consists of mass, stiffness, and (if necessary) damping matrices. The System also contains a CoordinateArray defining the degrees of freedom of the System, as well as a transformation that takes the System from its internal state degrees of freedom to physical degrees of freedom.
