I'm currently trying to convert a range of cells imported from a .csv from decimal to hex. However, I keep getting the error:

First argument must contain non-negative integers.

This is despite there not being any negative integers at all in the dataset. This is my current code:

f = @(x) dec2hex(round(x));
dataHex = [data(:, 1), varfun(f, data(:, 2:width(data)))];

Any help would be greatly appreciated.

You would get that message with that code if some of your values are nan.

Missing data could show up as NaN.
