The SparseArray
class uses public fields to hold the data for a sparse matrix in the Sparse Array format.
For a list of all members of this type, see ComplexSparseMatrix.SparseArray Members.

Public static (Shared in Visual Basic) members of this type are safe for multithreaded operations. Instance members are not guaranteed to be thread-safe.
This format came about as a means for storing sparse matrices. In this format, a sparse matrix is represented by two arrays of arrays. One array contains the references to the nonzero value arrays for each row of the sparse matrix. The other contains the references to the associated column index arrays.
As an example, consider the following complex sparse matrix:
InSparseArray
, this matrix can be represented by the two jagged arrays, values
and index
, where values
refers to the nonzero entries in A and index
to the column indices: Complex values[][] = { {new Complex(10.0, -3.0)}, {new Complex(10.0, 0.0), new Complex(-3.0, 2.0), new Complex(-1.0,-1.0)}, {new Complex(15.0, 5.0)}, {new Complex(-2.0, 0.0), new Complex(10.0, 1.0), new Complex(-1.0, -2.0)}, {new Complex(-1.0, 0.0), new Complex(-5.0, 7.0), new Complex(1.0, -3.0), new Complex(-3.0, 0.0)}, {new Complex(-1.0, 4.0), new Complex(-2.0, 1.0), new Complex(6.0, -5.0)} }; int index[][] = { {0}, {1, 2, 3}, {2}, {0, 3, 4}, {0, 3, 4, 5}, {0, 1, 5} };
