? Do you mean something other than
last3 = data(:, end-2:end);
I suspect that the last digit of the last w entry is missing, as you only have two 0's after the exponent, whereas all of the other values have 3 digits after the exponent.

Text files can be read in as character vectors, which can be stored into a character matrix by regular indexing.
A lot of the time it makes more sense to use readtable()
