MATLAB: Using maxk with named columns

maxvariable names

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).

One approach would be writing your own function:

function y=mink(A,k)
A=sort(unique(A));
y=A(1:k);
end

Call this function from command line as follows

A=1:10;
mink(A,3)

and the first three smallest elements will be displayed.

If you want to use min or max, then don't name a variable with the name min, or max.

which min -all
which max -all

What does that tell you?

Never use variable names that conflict with a function name.
