Unchanged on exit. X (input) Vector containing the values to be scattered from compressed form into full storage form. Unchanged on exit. INDX (input) - INTEGER Vector containing the indices of the compressed form. It is assumed that the elements in INDX are distinct and greater than zero. Unchanged on exit. Y (output) Vector whose elements specified by indx have been set to the corresponding entries of x. Only the elements corresponding to the indices in indx have been modified. 3rd Berkeley Distribution 7 Nov 2015 dsctr(3P)
