``````public static void Copy<T>(
this ILinearAlgebraOperations<T> operations,
MatrixTriangle storedTriangle,
int m,
int n,
Span2D<T> b
)

Parameters

operations  ILinearAlgebraOperations<T>

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.
```
```            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  Span2D<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).
```

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type ILinearAlgebraOperations<T>. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

Remarks

This method corresponds to the LAPACK routine DLACPY.
