Hi, i have a cell array like this. How can i know the index of the non empty cells? In this case the result should be index=[1 1 0].(Please note that i want the index, not what isinside the cell)
1×3 cell array
{[1]} {[1]} {0×0 double}

~cellfun(@isempty,C)
or
~cellfun('isempty',C)
The latter is faster (when run for 100000 iteration), so prefer that if you have a larger cell array.
