hi, I want to find he index value of non-zero vectors in a cell array. How do I do that ? TIA

for example E= 4×4 cell array

    [0]    [1×3 double]    [1×3 double]              []
    [0]              []    [1×3 double]    [1×3 double]
    [0]              []              []    [1×3 double]
    [0]              []              []              []

Then how do I find which cells if column two contains non-zero vectors?

x = cell(3) ;
x{1,1} = rand(2) ; 
x{2,2} = rand(3) ;
find(~cellfun(@isempty,x))
