public class DenseDComplexMatrix2D
extends DComplexMatrix2D
```
Dense 2-d matrix holding complex elements. Implementation:
Internally holds one single contigous one-dimensional array, addressed in row major. Complex data is represented by 2 double values in sequence, i.e. elements[idx] constitute the real part and elements[idx+1] constitute the imaginary part, where idx = index(0,0) + row * rowStride + column * columnStride. Note that this implementation is not synchronized.
Cells are internally addressed in row-major. Applications demanding utmost speed can exploit this fact. Setting/getting values in a loop row-by-row is quicker than column-by-column. Thus
```
 for (int row = 0; row < rows; row++) {
     for (int column = 0; column < columns; column++) {
         matrix.setQuick(row, column, someValue);
     }
 }
 
```
is quicker than
```
 for (int column = 0; column < columns; column++) {
     for (int row = 0; row < rows; row++) {
         matrix.setQuick(row, column, someValue);
     }
 }
 
```

    size - the number of cells the matrix shall have.
    
    Returns:
    a new matrix of the corresponding dynamic type.
  - setQuick
```
public void setQuick(int row,
            int column,
            double re,
            double im)
```
    Description copied from class: DComplexMatrix2D
    
    Sets the matrix cell at coordinate [row,column] to the specified value.
    Provided with invalid parameters this method may access illegal indexes without throwing any exception. You should only use this method when you are absolutely sure that the coordinate is within bounds. Precondition (unchecked): 0 <= column < columns() && 0 <= row < rows().
    
    Specified by:
    
    setQuick in class DComplexMatrix2D
    
    Parameters:
    row - the index of the row-coordinate.
    column - the index of the column-coordinate.
    re - the real part of the value to be filled into the specified cell.
    im - the imaginary part of the value to be filled into the specified cell.
  - setQuick
```
public void setQuick(int row,
            int column,
            double[] value)
```
    Description copied from class: DComplexMatrix2D
    
    Sets the matrix cell at coordinate [row,column] to the specified value.
    Provided with invalid parameters this method may access illegal indexes without throwing any exception. You should only use this method when you are absolutely sure that the coordinate is within bounds. Precondition (unchecked): 0 <= column < columns() && 0 <= row < rows().
    
    Specified by:
    
    setQuick in class DComplexMatrix2D
    
    Parameters:
    row - the index of the row-coordinate.
    column - the index of the column-coordinate.
    value - the value to be filled into the specified cell.
  - toArray
```
public double[][] toArray()
```
    Description copied from class: DComplexMatrix2D
    
    Constructs and returns a 2-dimensional array containing the cell values. The returned array values has the form re = values[row][2*column]; im = values[row][2*column+1] and has the same number of rows and columns as the receiver.
    The values are copied. So subsequent changes in values are not reflected in the matrix, and vice-versa.
    
    Overrides:
    
    toArray in class DComplexMatrix2D
    
    Returns:
    an array filled with the values of the cells.
  - vectorize
```
public DComplexMatrix1D vectorize()
```
    Description copied from class: DComplexMatrix2D
    
    Returns a vector obtained by stacking the columns of this matrix on top of one another.
    
    Specified by:
    
    vectorize in class DComplexMatrix2D
    
    Returns:
    a vector of columns of this matrix.
  - zMult
```
public DComplexMatrix1D zMult(DComplexMatrix1D y,
                     DComplexMatrix1D z,
                     double[] alpha,
                     double[] beta,
                     boolean transposeA)
```
    Description copied from class: DComplexMatrix2D
    
    Linear algebraic matrix-vector multiplication; z = alpha * A * y + beta*z. Where A == this.
    Note: Matrix shape conformance is checked after potential transpositions.
    
    Overrides:
    
    zMult in class DComplexMatrix2D
    
    Parameters:
    y - the source vector.
    z - the vector where results are to be stored. Set this parameter to null to indicate that a new result vector shall be constructed.
    
    Returns:
    z (for convenience only).
  - zMult
```
public DComplexMatrix2D zMult(DComplexMatrix2D B,
                     DComplexMatrix2D C,
                     double[] alpha,
                     double[] beta,
                     boolean transposeA,
                     boolean transposeB)
```
    Description copied from class: DComplexMatrix2D
    
    Linear algebraic matrix-matrix multiplication; C = alpha * A x B + beta*C. Matrix shapes: A(m x n), B(n x p), C(m x p).
    Note: Matrix shape conformance is checked after potential transpositions.
    
    Overrides:
    
    zMult in class DComplexMatrix2D
    
    Parameters:
    B - the second source matrix.
    C - the matrix where results are to be stored. Set this parameter to null to indicate that a new result matrix shall be constructed.
    
    Returns:
    C (for convenience only).
  - zSum
```
public double[] zSum()
```
    Description copied from class: DComplexMatrix2D
    
    Returns the sum of all cells.
    
    Overrides:
    
    zSum in class DComplexMatrix2D
    
    Returns:
    the sum.
  - index
```
public long index(int row,
         int column)
```
    Description copied from class: AbstractMatrix2D
    
    Returns the position of the given coordinate within the (virtual or non-virtual) internal 1-dimensional array.
    
    Overrides:
    
    index in class AbstractMatrix2D
    
    Parameters:
    row - the index of the row-coordinate.
    column - the index of the column-coordinate.
