# sparse

Updated:

sparse is used to create sdpvar objects with a certain structure.

### Syntax

x = sparse(i,j,s,n,m)


### Examples

Creating a diagonal matrix with every second diagonal element zero can be done as

x = sparse(1:2:2*n,1:2:2*n,sdpvar(n,1))


The command works exactly as the normal sparse command. Hence, help sparse will give you the details.
