*VITRP
*VITRP, ParR, ParT, ParI, ParJ, ParK
Forms an array parameter by interpolation of a table.
Argument Descriptions
ParRThe name of the resulting array parameter. See *SET for name restrictions.
ParTThe name of the TABLE array parameter. The parameter must exist as a dimensioned array of type TABLE (*DIM).
ParIArray parameter vector of I (row) index values for interpolation in
ParT.ParJArray parameter vector of J (column) index values for interpolation in
ParT(which must be at least 2D).ParKArray parameter vector of K (depth) index values for interpolation in
ParT(which must be 3D).
Notes
Forms an array parameter (of type ARRAY) by interpolating values of an array parameter (of type TABLE) at specified table index locations according to:
ParR = f(ParT, Parl, ParJ, ParK)
where ParT is the type TABLE array parameter, and
ParI, ParJ, ParK
are the type ARRAY array parameter vectors of index values for interpolation in
ParT. See the *DIM command for TABLE and ARRAY
declaration types. Linear interpolation is used. The starting array element number for the TABLE
array (ParT) is not used (but a value must be input). Starting array
element numbers must be defined for each array parameter vector if it does not start at the first
location. For example, *VITRP,R(5),TAB(1,1),X(2),Y(4) uses the second element
of X and the fourth element of Y as index values (row and column) for a 2D interpolation in TAB
and stores the result in the fifth element of R. Operations continue on successive array elements
(*VLEN, *VMASK) with the default being all successive
elements. Absolute values and scale factors may be applied to the result parameter
(*VABS, *VFACT). Results may be cumulative
(*VCUM). See the *VOPER command for details.
This command is valid in any processor.
