F_SSORTV/F_DSORTV Sort vector and return index vector
X REAL array, minimum length (N - 1) x |incx| + 1.
INCX Increment for the array x. A vector x having component
x
i
, i = 1,..., n, is stored in an array X() with increment
argument incx. If incx > 0 then x
i
is stored in
X (1 + (i - 1) x incx). If incx < 0 then x
i
is stored in
X (1 + (N - i) x |incx|). incx = 0 is an illegal value.
INCP Increment for the array p. A vector p having component
p
i
, i = 1,..., n, is stored in an array P() with increment
argument incp. If incp > 0 then p
i
is stored in
P (1 + (i - 1) x incp). If incp < 0 then p
i
is stored in
P (1 + (N - i) x |incp|). incp = 0 is an illegal value.
Output X Updated (sorted) array replaces the input.
P Permuted vector. Array of integers, minimum length
(N - 1) x |incp| + 1.
