character array from cell

mohammad movassat — Fri, 03 Jul 2009 20:45:03 -0400

Is there any way I can make a 2*1 character array from a 2*1 cell? I have a 2*1 cell:
f{1}=x+y+1 and f{2}=3x-5y+10, (x and y are syms) I want to have a char G<2*1> with exactly the same elements.

ps. the Matlab version I'm using is not very updated, so I'm looking for a way using basic commands in matlab not by specific toolboxes. any suggestions?

Thank you

Hello Mohammad,

If you pad the shorter character array with a sufficient number of blanks, you should be able to have that char array:

G(1,:) = 'x+y+1 '; % I put three blanks at the end.
G(2,:) = '3x-5y+10';

Best.

Thank you, but the issue is that the equations I have are much larger than the equations I showed above. My equations are generated after a couple of algebric manupulations and are vey long. and they are stored in cells. So I need to convert them to char by a command and I can not simply write them as char.

The equations I showed here were samples.

you've been given solutions to your problem earlier...
tell CSSM what ML version you have...

The solutions did not work, so I'm asking for an alternative.
the version I have is 7.0.4.

Hi,

You can loop through f like this.

% First determine the longest sequence
maxLength = 0;
for k = 1:length(f)
    currentSeqLength = length(char(f{k}));
    if currentSeqLength > maxLength
        maxLength = currentSeqLength;
    end
end

% Now that we know the maximum length, we can now loop through f and get
% the character array, say charF.

for k = 1:length(f)
    currentSeq = char(f{k});
    charF(k,:) = [currentSeq repmat(' ',1,maxLength-length(currentSeq))];
end

This should now work as you wanted.

Best.
