Sort rows of matrix by matching column with another matrix column

Hello All!

So I have two matrices, both the same size (88 rows and 31 columns).

In one matrix (A), I have the row data sorted in descending order based off of columns 28, 29 and 30 and in column 31 I have the identifiers for each individual.

In matrix B, I want to sort rows so that all of column 31 identifiers match column 31 of matrix A.

I'm more than happy to give an example, but the data set is pretty large and didn't want to copy and paste.

E.g., assuming everything in column 31 has a match

[~,x] = ismember(A(:,31),B(:,31));
Bsort = B(x,:);

Thank you!! I will try this out later and let you know but it should work. :)
