Hello everyone,
i have a problem with applying something on matlab which is:
for nn=1:a
stri=character(nn);
stri=strcat(stri,':');
stri=strcat(stri,num2str(probabilities(nn)));
stri=strcat(stri,':')
stri=strcat(stri,*My Problem In Here*)
stri=strcat(stri,':');
end
what i want to do is after getting the probability for each alpha and numebers and the spaces and the codeword i want to put them beside each other.
For example:
A:0.342:001100
D:0.432:011011
and so on.....
but when im trying to do that everytime its give me
A:0.342:' '
D:0.432:' '
without the codeword
what i have to do im kinda lost and i have to handout this project after tomorrow :S
thank you....
if there is any more information please ask! :)

Please show us your real code line that you represented here as
stri=strcat(stri,*My Problem In Here*)

im done now with the GUI is there a way to put :
for nn=1:a
stri=character(nn);
stri=strcat(stri,':');
stri=strcat(stri,num2str(probabilities(nn)));
stri=strcat(stri,':')
stri=strcat(stri,num2str(codewords{nn}(length(codewords{nn}):-1:1)))
stri=strcat(stri,':');
end
i dont want it to be in the same place where the rest of the output i want to be alone with another window like when i use pushbottom i want it to open another window written on it:
A:0.342:001100
D:0.432:011011
K:0.244:10010

You can use figure() to open a new window. In that new figure, create a uicontrol() of 'Style', 'edit', and 'Enable', 'disabled', and set its 'String' property to the text you want.

Change
stri=strcat(stri,codewords(nn))
to
stri=strcat(stri,char('0' + codewords(nn)))

when i changed it, its giving me this error:
??? Undefined function or method 'plus' for input arguments of type 'cell'.
Error in ==> HuffMan at 101
stri=strcat(stri,char('0' + codewords(nn)))

its working but its kinda flip the answer i don't know if its right to do that or its something wrong see what i mean :
The symbols, their probabilities and the allocated Huffman codewords are:
1 0.032258 1 0 1 0 0
2 0.064516 0 0 1 1
3 0.16129 1 1 1
4 0.096774 0 0 0
5 0.12903 0 1 0
6 0.032258 1 0 1 0 1

look what i did
i change the old one with this
stri=strcat(stri,num2str(codewords{nn}(length(codewords{nn}):-1:1)))
its giving me this :
