Error using - Integers can only be combined with integers of the same class, or scalar doubles.
Error in Code (line 27) data = data - repmat(mn,1,N);
Here is the code snip, where I am subtracting off the mean of some matrices:
mn = mean(data,2);
data = data - repmat(mn,1,N);
I tried casting the new data matrix to an int16 but that gave the same error, not sure what to cast it to, to avoid error.

I added my answer below.
Are the matrices square? If they're not square, the * operator is matrix multiplication, if they're like NxM this is asking Matlab to do NxM * NxM which doesn't work. If you want to multiply them component-wise, the operator is .*.

I think you should post another question to cover this, and give more background. I don't really understand what you're trying to do here, so you might want to explain very precisely what you're trying to accomplish, and what the objects you're working with are. (For instance, why are you trying to get the eigenvalues of a non-square matrix? Which operation made it non-square; it wasn't subtracting off the means.)

i have the same problem please help me!!.
Error using mod
Integers can only be combined with integers of the same class, or scalar doubles.
Error in trial>decryption_Callback (line 457) m1(l)=mod(c2,n); code: c1=reshape(c,1,[]); s=numel(c1); m1=c1; c2=c1; for l=1:s c2(l)=c1(l)^msk; m1(l)=mod(c2,n); end

Error???????????????????????
%rough dark channel computation%
%a=imread('D:\Image processing project\image\hazy.jpg');
a=imread('D:\Image processing project\contrast\dark channel prior\dehaze_code\dehaze_code\inputImgs\forest_input.png');
[ht,wt,~]=size(a);
patchSize=15;
padSize=7;
JDark=zeros(ht,wt);
imj=padarray(a,[padSize padSize],inf);
for i=1:ht
for j=1:wt
patch=imj(i:(i+padSize-1),j:(j+padSize-1),:);
JDark(i,j)=min(patch(:));
end
end
atmSum=zeros(1,3);
imsize=ht*wt;
numpx=floor(imsize/1000);
JDarkVec=reshape(JDark,imsize,1);
ImVec=reshape(a,imsize,3);
[JDarkVec,indices]=sort(JDarkVec);
indices=indices(imsize-numpx:end);
atmSum=zeros(1,3);
for ind=1:numpx
atmSum=atmSum+ImVec(indices(ind),:);
end
A=atmSum/numpx;
figure;
imshow(uint8(A));
So what is the problem with the atmSum, it is not working. Anybody wants to solve this problem are always welcome.
or email me: lokesh.singh.in@gmail.com
Thanks
