*VSCFUN
*VSCFUN, ParR, Func, Par1
Determines properties of an array parameter.
Argument Descriptions
ParRThe name of the resulting scalar parameter. See *SET for name restrictions.
FuncFunctions:
- MAX --
Maximum: the maximum
Par1array element value.- MIN --
Minimum: the minimum
Par1array element value.- LMAX --
Index location of the maximum
Par1array element value. ArrayPar1is searched starting from its specified index.- LMIN --
Index location of the minimum
Par1array element value. ArrayPar1is searched starting from its specified index.- FIRST --
Index location of the first nonzero value in array
Par1. ArrayPar1is searched starting from its specified index.- LAST --
Index location of the last nonzero value in array
Par1. ArrayPar1is searched starting from its specified index.- SUM --
Sum:
Par1(the summation of thePar1array element values).- MEDI --
Median: value of
Par1at which there are an equal number of values above and below.- MEAN --
Mean: (σ Par1)/NUM, where NUM is the number of summed values.
- VARI --
Variance: (σ ((
Par1-MEAN)**2))/NUM.- STDV --
Standard deviation: square root of VARI.
- RMS --
Root-mean-square: square root of (σ (
Par1**2))/NUM.- NUM --
Number: the number of summed values (masked values are not counted).
Par1Array parameter vector in the operation.
Notes
Operates on one input array parameter vector and produces one output scalar parameter according to:
ParR = f(Par1)
where the functions (f) are described below. The starting array element number must be defined for the array parameter vector. For example, *VSCFUN,MU,MEAN,A(1) finds the mean of the A vector values, starting from the first value and stores the result as parameter MU. Operations use successive array elements (*VLEN, *VMASK) with the default being all successive array elements. Absolute values and scale factors may be applied to all parameters (*VABS, *VFACT). Results may be cumulative (*VCUM). See the *VOPER command for details.
This command is valid in any processor.
