sparseToDense

public static void sparseToDense(MatrixBlock r,
 int k)

Convert the given matrix block to a Dense allocation.

There is two exceptions:

• Empty input blocks are not modified.
• Calls where the input block is already dense is ignored.

Parameters:

r - The matrix block to modify, to dense.

k - The parallelization degree.
