"krypt" is a text file which I want to convert to numbers, sort, and then only keep the characters that are letters (characters with number 65 to 90). Neither of the two examples below works. It works to put sort2=sort(sort~=32) but that only removes the blankspaces. There are a lot of other symbols that I dont want in "sort2" as well.
%"krypt" is a text file
sort=double(unique(krypt));
sort2=sort(sort==65:90);
%Or
sort2=any(sort(sort==65:90))

You could do
intersect(yourArray,65:90)
You also should not use sort as a variable name, because it is a MATLAB keyword. You will quickly get confused and/or have an error when you later try to use the sort command.
