| var | a variable |
| Parameter | Description |
|---|---|
| res | a logical: true or false |
issparse returns a logical 1 if the argument is a sparse array and a logical 0 otherwise.
The test is based on sparse storage, not on the value class. Sparse double, single, logical, complex double, and complex single arrays all return true.
Full arrays return false even when they contain mostly zero values.
A = 1;
res = issparse(A)B = sparse(1);
res = issparse(B)S = sparse(single([1 + 2i 0; 0 0]));
res = issparse(S)| Version | Description |
|---|---|
| 2.0.0 | documented sparse single and complex single behavior |
| 1.0.0 | initial version |
