MATLAB: Sum of Cell Array [Besides for loop]

Question

I'm having difficulty trying to solve this problem. Suppose:

testvalue = {[1]     []     []
             [1]    [1]    [1]
             [1]     []     []
             [1]    [1]     []}

I want to sum the contents of each row, which should give:

        1+nil+nil=1
        1+1+1=3
        1+nil+nil=1
        1+1+nil=1

I tried using for loop but it upon adding cumulative sum with [], the new sum becomes []. Can someone shed some light? Thanks.

Answer 1

T = testvalue;
T(cellfun(@isempty,T)) = {0};
sum( cell2mat(T), 2)
