How to fix an error from accumarray?

I have val and subs variables as I shown you and I try to group subs values into same cell array asnd return val to me. When I run this code

    A = accumarray(subs,val,[],@(x) {x})

the Matlab software shows this error "Error using accumarray First input SUBS must contain positive integer subscripts.". Thus, I want to know how can I fix it out ?

Thanks in advance
