WM(I, J)

Description

The WM function computes the magnitude of the total relative rotational velocity between two markers.  The first argument, marker I, must be specified.  The second argument, marker J, is optional.

Example

<Post_Request

    comment          = "WM-WDTM-HAVSIN-FORSIN-DIM-ACOS"

    id               = "3"

    type             = "EXPRESSION"

    expr1            = "NULL"

    expr2            = "WM(30102010)"

    expr3            = "WDTM(30102010)"

    expr4            = "HAVSIN(TIME,1.,0.,4.,1.)"

    expr5            = "NULL"

    expr6            = "FORSIN(TIME,0.1,6.28,0.1,0.2)"

    expr7            = "DIM(TIME,1.0)"

    expr8            = "ACOS(COS(TIME))"

Arguments

I

The marker whose velocity is to be computed.

J

The marker with respect to which the velocity is to be computed.  This argument is optional.  If omitted, it defaults to the ground coordinate system.
