I have a matrix RG_table with two columns. I want to sort the rows of the matrix in descending order depending on column 2. Column 2 has values which are non integers. I tried it with sortrows, but I get this error:
Column sorting vector must contain integers with absolute value between 1 and the number of columns in the first argument.
score_sort = sortrows(RG_table, 2, 'descend');
Does anybody know what to do?

Well, no...we have no way to know any such thing.
One guess would be the data on the server isn't the same as that locally...
Again without much more detail and context we're shooting in the dark here.
ADDENDUM
At a minimum, put
whos RG_table
in the function/script before executing the sortrows line on each platform. That will at least be a chance at figuring out what it is you're looking at.

Basically the message is telling you that the table is either empty or has only 1 column.
