mphray

Evaluate expressions on particle and ray trajectories.

pd = mphray(model,'expr',{e1,...,en},...)

pd = mphray(model) returns particle position and particle velocity at all time steps stored in the first particle dataset.

pd = mphray(model,'expr',{e1,...,en},...) returns particle position, particle velocity and expressions e1,...,en evaluated on particle or ray trajectories.

pd is a structure with fields p, v, d#, t, expr, and unit.

•

The field p contains the position of the particles.

•

The field v contains the velocity of the particles.

•

The field d# contains the result of evaluation #.

•

The field t contains the time for evaluation.

•

The field expr contains the evaluated expressions.

•

The field unit contains the unit of evaluations.

The function mphray accepts the following property/value pairs:

Table 6-27: property/value pairs for the mphray command
