suppose i have a matrix x and the second row has values ranging from 0.2 to 102 and weightage has to be assigned to these depending on the mean. the values close to the mean should have highest weightage and progressively decrease as it goes farther.

You said that the values closest to the mean should have the highest weight . sorted_distance tells you exactly how far values are from the mean, arranged in increasing distance . sort_order tells you what the original order was. For example if the first entry of sorted_distance is 0.063 and the first entry of sort_order is 19 then that tells you that the entry that was closest to the mean was aa distance of 0.063 from the mean and that it was the 19th row in the original data that had that entry .
Now it is up to you to decide how a particular distance from the mean shold be transformed into a weight .
