How to create 3D matrix with empty cells

10 views (last 30 days)
So I am currently trying to make a 3D matrix(300x300x300) and want the cells to be empty ([]) so i can input data into it later. I know I can use the zeros function to create an 3D matrix of zeros but I need the cells to be empty as it would affect some of the calculations I am using to fill the matrix with data if the cells had zeros in them rather than being empty it would not work.
If you know a way to make an empty 3D matrix please let me know.
Any help is appreciated :)

cell(3,3,3) % replace 3 with 300 for you
I'm still afraid you'll be soon in trouble if you ask such question about easy data creation.
