The expression to the left of the equals sign is not a valid target for an assignment. ...? Error in line 3rd, " minOfBlocks = zeros(16,16); " ... Help me plz

I=imread('pepper.png');

c = mat2cell(I, [32 32 32 32 32 32 32 32 32 32 32 32 32],...[32 32 32 32 32 32 32  32 32 32 32 32]);

minOfBlocks = zeros(16,16);

subplot(1,2,1);

imshow(I);

title('Original Image', 'FontSize', 30);

for i=1:16

  for j=1:16

    a = c{i,j};

    minOfBlocks(i,j)=min(a(:));

  end

end

I am having trouble reproducing your error. I see nothing explicitly wrong with the third line of code. Also, no need to say "Help me plz"; it won't get you answers any faster, I promise.

Did you literally type ... in the middle of the second line? If so, MATLAB is waiting for you to finish that function call on the next line and assigning a value into a variable in the middle of a function call is not allowed. Either remove the ellipsis (...) or move the code that follows it onto the next line.

The ellipsis "..." is an implicit comment starter also. So everyting right from '...' is ignorend, such that Matlab try to run:

c = mat2cell(I, [32 32 32 32 32 32 32 32 32 32 32 32 32],...
                 minOfBlocks = zeros(16,16);

As Steven told already insert a line break after the '...':

c = mat2cell(I, [32 32 32 32 32 32 32 32 32 32 32 32 32],...
                [32 32 32 32 32 32 32 32 32 32 32 32]);
minOfBlocks = zeros(16,16);

By the way: The bunch of "32" is hard to debug. This is easier to read:

c = mat2cell(I, repmat(32, 1, 13), repmat(32, 1, 12));

Sir, Actually i am new in MATLAB.. I will replace c = mat2cell(I, [32 32 32 32 32 32 32 32 32 32 32 32 32],...[32 32 32 32 32 32 32 32 32 32 32 32]); with c = mat2cell(I, repmat(32, 1, 13), repmat(32, 1, 12));

then the error is Error using mat2cell (line 80) Number of input vector arguments, 2, does not match the input matrix's number of dimensions, 3.

Error in blks (line 17) c = mat2cell(I, repmat(32, 1, 13), repmat(32, 1, 12));
