WebSep 15, 2024 · I know of the way to first replace all of empty cells with 0 and they use the find and cellfun function. But is there a simpler way? Lets say A= {2 5 0 10 0 [] 22 0 13} index=find (~cellfun (@isempty,A)) % index for non-empty cells Is there a way to find indexes for those who contain positive numbers only? Thanks btw using MatLab 2015a
