Copy(MatrixTriangle, Int32, Int32, Array2D<T>, Array2D<T>)

Copies all or part of a two-dimensional matrix A to another matrix B.

C# 
public virtual void Copy(
	MatrixTriangle storedTriangle,
	int m,
	int n,
	Array2D<T> a,
	Array2D<T> b
)

Parameters

storedTriangle  MatrixTriangle
            Specifies the part of the matrix A to be copied to B.
            = 'U':      Upper triangular part
            = 'L':      Lower triangular part
            Otherwise:  All of the matrix A
m  Int32
            The number of rows of the matrix A.  M >= 0.
n  Int32
            The number of columns of the matrix A.  N >= 0.
a  Array2D<T>
            Dimension (LDA,N)
            The m by n matrix A.  If UPLO = 'U', only the upper triangle
            or trapezoid is accessed; if UPLO = 'L', only the lower
            triangle or trapezoid is accessed.
            
            The leading dimension of the array A.  LDA >= max(1,M).
b  Array2D<T>
            Dimension (LDB,N)
            On exit, B = A in the locations specified by UPLO.
            
            The leading dimension of the array B.  LDB >= max(1,M).
