identify rows with [] within a cell

Hi! Is there any way to identify rows with [] within a cell? Something that is analogous to 'find'.

[rr,cc] = find(M(:,1) == []);

You should use isempty for checking if an array (of any data type) is empty or not -

load('M.mat')

M

M = 6×1 cell array
    { 0×2 double}
    {36×2 double}
    {22×2 double}
    { 3×2 double}
    { 0×2 double}
    { 2×2 double}

cellfun('isempty', M)

ans = 6×1 logical array
   1
   0
   0
   0
   1
   0
