I have a cell of cells. The inner cell is a 1 x 1 and contains a vector. The vector in each inner cell might be of different length. How do I convert this inner cell into an ordinary vector?

在 MATLAB Online 中打开

testcell = {{[1]} {[2 3]} {[4 5 6]}}
testcell = 1×3 cell array
    {1×1 cell}    {1×1 cell}    {1×1 cell}
output = cellfun(@(C) C{1}, testcell, 'uniform', 0)
output = 1×3 cell array
    {[1]}    {[2 3]}    {[4 5 6]}
testcell{2}
ans = 1×1 cell array
    {[2 3]}
output{2}
ans = 1×2
