format for its use is
y = issparse(x)
This function returns true if x is encoded as a sparse
matrix, and false otherwise.
Example
Here is an example of using issparse:
--> a = [1,0,0,5;0,3,2,0]
a =
1 0 0 5
0 3 2 0
--> issparse(a)
ans =
0
--> A = sparse(a)
A =
1 1 1
2 2 3
2 3 2
1 4 5
--> issparse(A)
