for j=2:length(Y)

if length(Y{1,j})~=1

    z=Y{1,j}

    zz=cellstr(z)

As the error clearly states, the input to cellstr() must be a string, which it is not.

What is the content of Y? Please attach the data corresponding to Y.

Y

I assume you want to convert each cell into cell string (except the elements which are already a cell string)?

Actually, I want to implement hierarchical clustering algorithm in MATLAB. Each character means the cluster name.

Yes
