Returns whether the given sparse matrix is in default state.
- Parameters
-
m | The sparse matrix to be tested for its default state. |
- Returns
- true in case the given matrix is component-wise zero, false otherwise.
This function checks whether the compressed matrix is in default state. For instance, in case the matrix is instantiated for a built-in integral or floating point data type, the function returns true in case all matrix elements are 0 and false in case any matrix element is not 0. The following example demonstrates the use of the isDefault function:
