SORTLIND (v2.1)

sorts input and returns linear indices for parallel sorting

Description

[Y,I] = SORTLIND(X, ...) behaves (almost) exactly the same as the standard matlab function SORT, except that it returns linear indices so that Y equals X(I) independent of the dimensions and size of X.
(Note that [Y,I] = sort(X,...) returns sub-indices in I.)

Very nice. This is exactly what I need :).

The program has a bug when I tried to sort ten random numbers, the program went to create three dimentional array I gave the following statments
x=rand(1,10)
xx=sortlind(x)
try them and see what happens

Dear Aasim,

I could not replicate your bug. The commands "x = rand(1,10) ; xx = sortlind(x); "
nicely returns an ordered 1-by-10 matrix called xx. Moreover, when called like this, SORTLIND just passes everything to SORT and does nothing else! What does sort(x) give you? Jos
