Variables

const Real SimTK::NaN

const Complex SimTK::I
 We only need one complex constant, i = sqrt(-1). For the rest just multiply the real constant by i, or convert with Complex(the Real constant), or if you need an address you can use NTraits<Complex>::getPi(), etc. More...
 

Detailed Description

This is a user-includable header which includes everything needed to make use of SimMatrix Scalar code.

More commonly, this will be included from within Matrix code.
