I want to locate the maximum number in a matrix.
For instance
A = magic(5)
to show the highest value I use maxk(A,1)
when I assign variable names to the table, maxk doesnt work, probably because there are now also names in the table.
How do I get this to work?

If all the columns in the table are numeric
max_val = max(T{:,:})
Note maxk(x,1) is same as max(k).
