# SparseMatrix_Complex_Double

A type representing a sparse complex matrix.

## Declaration

```swift
struct SparseMatrix_Complex_Double
```

## Overview

Overview data is the array of values in the non-zero blocks of the matrix stored contiguously, each block in column-major order. If there are N structural non-zero blocks in the matrix, data holds blockSize * blockSize * N doubles. term  structure The symbolic structure of the matrix. term  data The numerical values of the matrix. If structure.blockSize > 1, blocks are stored contiguously in column-major format.
