{
Frisbee.SimulationState st = new Frisbee.SimulationState
{
VX = 1,
VY = 1,
Theta = Math.PI / 4
};
Matrix<double> transformation =
new SparseMatrix(new [,]
{
{st.CosTheta, st.SinTheta*st.SinPhi, -st.SinTheta*st.CosPhi},
{0, st.CosPhi, st.SinPhi},
{st.SinTheta, -st.CosTheta*st.SinPhi, st.CosTheta*st.CosPhi}
});
SparseVector c3 = new SparseVector(transformation.Row(2));
SparseVector velocity = new SparseVector(new[] { st.VX, st.VY, st.VZ });
double velocityMagnitude = velocity.Norm(2);
double velocityC3 = velocity.DotProduct(c3);
Vector<double> vp = velocity.Subtract(c3.Multiply(velocityC3));
double vpMagnitude = vp.Norm(2);
