DLASRT sorts numbers in increasing or decreasing order.
Sort the numbers in D in increasing order (if ID = 'I') or in decreasing order (if ID = 'D' ). Use Quick Sort, reverting to Insertion sort on arrays of size <= 20. Dimension of STACK limits N to about 2**32.
ID is CHARACTER*1 = 'I': sort D in increasing order; = 'D': sort D in decreasing order.
N is INTEGER The length of the array D.
D is DOUBLE PRECISION array, dimension (N) On entry, the array to be sorted. On exit, D has been sorted into increasing order (D(1) <= ... <= D(N) ) or into decreasing order (D(1) >= ... >= D(N) ), depending on ID.
INFO is INTEGER = 0: successful exit < 0: if INFO = -i, the i-th argument had an illegal value
