unable to perform assignment because the size of the left side

can someone fix my error?

"Unable to perform assignment because the size of the left side is 1-by-3855 and the size of

the right side is 3616-by-1."

function [Output,kelas] = EkstraksiCurvature(folder, baseFileName, delta, kelas)
% fungsi ini digunakan untuk melakukan ekstraksi curvature
% objek dalam sebuah gamabr dengan solid background

fullFileName = dir(fullfile(folder, baseFileName));
JumFile=size(fullFileName,1);
for N=1:JumFile
   citra = imread(fullfile(folder, fullFileName(N).name)); 
   
   %PREPROCESSING
   Tepi = prepross(citra);
   x = Tepi(:,1);
   y = Tepi(:,2);
   
   %DIFFERENTIAL
   [dx1,dx2] = differential(x,delta);
   [dy1,dy2] = differential(y,delta);
   Turunan = [dx1, dy1, dx2, dy2];
   
   %EKSTRKASICURVATURE
   k = curvature(Turunan);
   Output(N,:)=k;
   Kelas(N,1) = kelas;
end
end

The error is clear - You are trying to assign a 3616x1 array to a placeholder of size 1x3855, which is not possible.

Since we don't have the inputs/data you are working nor any user-defined functions you are using, we can't run your code to see what exactly the problem is and suggest anything.

Nor do we know where the error occurs.

If you need help, you need to provide all the relevant information.

I think I can figure it out what I had to do with this. Thx for your answer Dyuman. Really appriciete.

Sound's like you were able to solve your problem, but in case you weren't aware of it MATLAB provides very nice debugging tools to let you step through your code and examine variables at specific points in the execution, https://www.mathworks.com/help/matlab/matlab_prog/debugging-process-and-features.html

If you don't already do so, I suggest that whenever you run into these kinds of errors, you set a breakpoint just before the point where the error occurs (the error message shows the line where the error occurs, and you can click on the error message to jump to that point in your code). Then examine the variables, for example hover over them with the mouse, or look at the workspace variables in the workspace browser: https://www.mathworks.com/help/matlab/ref/workspacebrowser.html

In particular for an error message like yours you can check the array dimensions and make sure they make sense, and are what you expected.
