Hello everyone, here is the partial code that creates above error:
counter=1;
accessRow=0;
for r=1:length(m)
accessVector=m(r);
newAccessVector=cell2mat(accessVector);
accessRow=accessRow + newAccessVector;
SplitFeaturesRow{r}=cidxE(counter:accessRow)
counter=1+accessRow;
vocabsize=1:500;
freq{r}=histc(SplitFeaturesRow{r},vocabsize);
combineFreq=horzcat(freq{:});
end
Referring code above, m output= 474 X1 cell but r output = 472 . I wonder why r did not get 474 as it should follow the length of m. I think this is the reason why I got that error message. But how to correct r?

Okay... but are you sure you want to do that horzcat() within the loop? Every iteration of the loop you are overwriting the complete combineFreq variable

Try:
out = cat(1, freq{:})

Error using cat Dimensions of matrices being concatenated are not consistent.
Error in (line 69) combineFreq = cat(1, freq{:});
