if i get string as an input in COM1 and i have to make a shape according to that string. the string has characters- A,A',B,B',C,C',D,D' and these characters represent lines which have to be drawn. A represents line in upward direction of length say x, then A' represents line in upward direction but the length of the line of half of A ie, x/2, similarly with the other characters, where A represents upward line, B-downward line, C-left line and D- right line. Ex: if the string i receive a string AD'BA'C' then the output should be "A" in segmented form

I'm not going to given you the entire code, but to get you started, here's how you can do the parse:
a = 'AD''BA''C'''; %sample input string
%separate into various characters
chars = regexp(a, '[ABCD](''*)', 'match'); %characters are in a cell array
for k=1:length(chars),
c = chars{k}; %for each character
%fill in the plotting code here!
end

Hint:
I(curx:curx+L,:) = 1; %line of length L drawn vertically
