MATLAB: Dimensions of matrices being concatenated are not consistent

errorMATLABmatricesstringvertcat

% How can I display the result in the following example. Not all time the strings are equals,
%but I need to display one below the other even at the end one even one is missing, it is possible?
c=[23;33;33;44;55;66;77;88;99;00;11;22;33;44];%  14 numbers



d=[23;33;33;44;55;66;77;88;34;00;11;44;33;44];%  14 numbers

f=[23;33;33;44;53;66;77;88;99;04;11;22;33;44];%  14 numbers
g=[23;33;33;45;53;66;77;88;99;04;11;22;33;]; % as you can see this string is only 13 numbers

Error: 
Error using vertcat
Dimensions of matrices being concatenated are not consistent.
Error in Runscript (line 11)
result=[c;d;e;f;g];
%%I would like the result like in following picture below

You cannot have holes in a matrix so append NaN at the end. By the way you refer to them as string but in fact they are double array. But if they were string appending "" at the end of g would do it.

MATLAB: Printing a cell array of strings and numbers with fprintf

There is no need for the loops, just transpose the cell array and then use {:} to convert it to a comma separated list. fprintf repeatedly applies the format string to all of the input arguments, so it does the looping for you!

D = C';
fprintf('%s %s %d %d %d %3.2f\n',D{:})

and it prints this text in the command window:

Andie,A. a5123 85 100 90 91.67
Ellen,E. e1567 86 88 89 87.67
Francine,F. f2321 85 87 90 87.33
George,G. g3455 70 65 72 69.00
Ike,I. i4678 68 45 92 68.33
Madeleine,M. m2134 55 47 59 53.67
Tabitha,T. t5321 20 58 65 47.67

We can also align the columns:

D = C';
D(2:end+1,:) = D;
D(1,:) = {max(cellfun('length',C(:,1)))};
fprintf('%*s %3s %3d %3d %3d %3.2f\n',D{:})

to create this:

      Andie,A. a5123  85 100  90 91.67
      Ellen,E. e1567  86  88  89 87.67
   Francine,F. f2321  85  87  90 87.33
     George,G. g3455  70  65  72 69.00
        Ike,I. i4678  68  45  92 68.33
  Madeleine,M. m2134  55  47  59 53.67

MATLAB: Rotating and saving images to folder: error during loop

Teshan:

I believe the problem comes about because you are, in subsequent runs, processing images from a prior run. You should either skip those images, like I did in my code below, or write those images to a folder different than your input folder.

folder = pwd;
S = dir(fullfile(folder,'*.png'));
fprintf('Found %d PNG files.\n', length(S));
hFig = figure;
hFig.WindowState = 'maximized';
angles = [90, 180, 270];
for k = 1 : 3
	originalFilename = fullfile(folder, S(k).name);
	[~, baseFileNameNoExt, ~] = fileparts(lower(originalFilename))
	originalImage = imread(originalFilename);
	fprintf('\nRead in %s.\n', originalFilename);
	subplot(2, 2, 1);
	imshow(originalImage);
	title(['Original image : ', S(k).name], 'FontSize', 15);
	
	% Skip files that are the outputs from prior runs.  
	% They will contain '-n.png'
	if endsWith(baseFileNameNoExt, ' -1') || ...
	endsWith(baseFileNameNoExt, ' -2') || ...
	endsWith(baseFileNameNoExt, ' -3')
		continue; % Skip this image.
	end
	
	for angleIndex = 1 : 3
		thisAngle = angles(angleIndex);
		rotatedImage = imrotate(originalImage, thisAngle);
		subplot(2, 2, angleIndex + 1);
		imshow(rotatedImage);
		% Create new name with -1, -2, or -3 appended to the original base file name.
		rotatedName = sprintf('%s -%d.png', baseFileNameNoExt, angleIndex);
		title(rotatedName, 'FontSize', 15);
		fullFileName = fullfile(folder, rotatedName);
		imwrite(rotatedImage, fullFileName);
		fprintf('    Wrote out %s.\n', fullFileName);
	end
	
	promptMessage = sprintf('Do you want to Continue processing,\nor Quit processing?');
	titleBarCaption = 'Continue?';
	buttonText = questdlg(promptMessage, titleBarCaption, 'Continue', 'Quit', 'Continue');
	if contains(buttonText, 'Quit')
		break;
	end
end
close(hFig);
