◆ SparseCompressedBase()

template<typename Derived>

Eigen::SparseCompressedBase< Derived >::SparseCompressedBase ( )

inlineprotected

Default constructor. Do nothing.

Member Function Documentation

◆ coeffs() [1/2]

template<typename Derived>

Map< Array< Scalar, Dynamic, 1 > > Eigen::SparseCompressedBase< Derived >::coeffs ( )

inline

Returns: a read-write view of the stored coefficients as a 1D array expression

Warning: this method is for compressed storage only, and it will trigger an assertion otherwise.

Here is an example:

SparseMatrix<double> A(3, 3);
A.insert(1, 2) = 0;
A.insert(0, 1) = 1;
A.insert(2, 0) = 2;
A.makeCompressed();
cout << "The matrix A is:" << endl << MatrixXd(A) << endl;
cout << "it has " << A.nonZeros() << " stored non zero coefficients that are: " << A.coeffs().transpose() << endl;
A.coeffs() += 10;
cout << "After adding 10 to every stored non zero coefficient, the matrix A is:" << endl << MatrixXd(A) << endl;

and the output is:

The matrix A is:
0 1 0
0 0 0
2 0 0
it has 3 stored non zero coefficients that are: 2 1 0
After adding 10 to every stored non zero coefficient, the matrix A is:
 0 11  0
 0  0 10
12  0  0
