Parameters

matrix: Type: SystemDouble
The matrix for the linear problem.
diagonalRightSide: Type: SystemDouble
The right side b.
leastSquares (Optional): Type: SystemBoolean
True to produce a solution even if the matrix is singular; false otherwise. Default is false.

Return Value

Type: Double

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type . 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

Please note that this does not check if the matrix is non-singular before attempting to solve. If a least squares solution is desired in case the matrix is singular, pass true to the leastSquares parameter when calling this function.
