Sparse Matrix in Altair Compose

Recommended Posts

Hi Rodolfo,

 

You can use the function sparse.

 

For example if you have a full matrix you can convert it in this way:

 

sparse(eye(6))

 

Or you can create a sparse matrix specifying the row & col index and the related value. For example:

 

m = [1 4 10];

n = [ 2 6 8];

val = [1 3 8];

Matrix = sparse(m,n,val)

 

Hope it helps,

 

Lorenzo
