# SparseSolve(_:_:_:_:)

Solve AX=B using the specified iterative method for complex double values.

## Declaration

```swift
func SparseSolve(_ method: SparseIterativeMethod, _ ApplyOperator: @escaping (Bool, CBLAS_TRANSPOSE, DenseMatrix_Complex_Double, DenseMatrix_Complex_Double) -> Void, _ B: DenseMatrix_Complex_Double, _ X: DenseMatrix_Complex_Double) -> SparseIterativeStatus_t
```

## Parameters

- `method`: (Input) Iterative method specification, eg return value of SparseConjugateGradient().
- `ApplyOperator`: ApplyOperator(accumulate, trans, X, Y) should perform the operation Y = op(A)X if accumulate is false, or Y += op(A)X if accumulate is true.
- `B`: The right-hand sides B to solve for. If A has dimension m x n, then B must have dimension m x nrhs, where nrhs is the number of right-hand sides to find solutions for.
- `X`: On entry, initial guess for solution, on return the solution. If A has dimension m x n, and B has dimension m x nrhs, then X must have dimension n x nrhs. If no good initial estimate is available, user should set the initial guess to be the zero vector.
