Hello, is possible to create a sparse matrix type CELL?

I need to insert some strings in a matrix with many many
zeros empty cell.

Thanks

No. It is not possible in matlab.

However, you can solve this problem simply
enough.

1. Store your elements in a simple linear cell array,
one after the other.

2. Create a sparse matrix of indexes into the linear
index of your cell array.

HTH,
John
