I have 20 land/sea masks (gridded data at 360x180 degrees). I want to save them into a cell array called A. In Matlab I would do this:  
A{1} = grid1;  
A{2} = grid2;  
…

How could I do the same thing in Julia, so that I could save the data into my hard disk?

Many thanks!

no idea what a cell array is, but it sounds like you just want to save 20 x (360\*180) matrix to disk?

In Julia you can for an array of whatever, even arrays (matrices):

```julia
