We are having trouble deleting and spacing characters in our Matlab virtual keyboard. When we want to press delete, the word delete appears in the keyboard instead of actually deleting characters. When we want to space out the characters in Matlab, the word space appears in the matlab code instead of actually spacing out the characters.

Hi,
Just a naive try at what you asked, i hope it helps!
function AddLetter(letter)
%Called when letter pressed
%Add letter to string
str = get(hEdit,'string');
if strcmp(letter,'SPACE')
str(end+1) = ' ';
elseif strcmp(letter,'DELETE')
str(end) = '';
else
str = horzcat(str,letter);
end
set(hEdit,'string',str);
drawnow;
%NOTE: Obviously, you'll need to add features here such as
%backspace etc.
end

On my end, It works like a backspace key. I have just used the following logic:
>> str = 'hello world';
>> str(end) = '' %empty quote
str =
'hello worl'
