Represents an arbitrarily sized matrix of double-precision floating point numbers. If you are working with a 4x4 matrix, then you may want to use the Transform class instead.

Public Class Matrix
	Implements IDisposable

The Matrix type exposes the following members.

	Name	Description
	Matrix(Transform)	Initializes a new instance of the matrix based on a 4x4 matrix Transform.
	Matrix(Int32, Int32)	Initializes a new instance of the matrix.

	Name	Description
	ColumnCount	Gets the amount of columns.
	IsColumnOrthogonal	Gets a value indicating whether the matrix is column orthogonal.
	IsColumnOrthoNormal	Gets a value indicating whether the matrix is column orthonormal.
	IsRowOrthogonal	Gets a value indicating whether the matrix is row orthogonal.
	IsRowOrthoNormal	Gets a value indicating whether the matrix is row orthonormal.
	IsSquare	Gets a value indicating whether this matrix has the same number of rows and columns. 0x0 matrices are not considered square.
	IsValid	Gets a value indicating whether this matrix is valid.
	Item	Gets or sets the matrix value at the given row and column indixes.
	RowCount	Gets the amount of rows.

	Name	Description
	BackSolve	Solves Mx=b where M is upper triangular with a unit diagonal and b is a column of values.
	BackSolvePoints	Solves Mx=b where M is upper triangular with a unit diagonal and b is a column of 3d points.
	Dispose()	Actively reclaims unmanaged resources that this instance uses.
	Dispose(Boolean)	For derived class implementers. This method is called with argument true when class user calls Dispose(), while with argument false when the Garbage Collector invokes the finalizer, or Finalize() method. You must reclaim all used unmanaged resources in both cases, and can use this chance to call Dispose on disposable fields if the argument is true. Also, you must call the base virtual method within your overriding method.
	Duplicate	Create a duplicate of this matrix.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Passively reclaims unmanaged resources when the class user did not explicitly call Dispose(). (Overrides Object.Finalize().)
	GetHashCode	Gets the hash code for this matrix. The hash code will change when the matrix changes so you cannot change matrices while they are stored in hash tables. (Overrides Object.GetHashCode().)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Invert	Modifies this matrix to become its own inverse. Matrix might be non-invertible (singular) and the return value will be false.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	RowReduce(Double, Point3d[], Double)	Row reduces a matrix as the first step in solving MX=b where b is a column of 3d points.
	RowReduce(Double, Double, Double)	Row reduces a matrix to calculate rank and determinant.
	RowReduce(Double, Double[], Double)	Row reduces a matrix as the first step in solving MX=b where b is a column of values.
	Scale	Modifies the current matrix by multiplying its values by a number.
	SetDiagonal	Sets diagonal value and zeros off all non-diagonal values.
	SwapColumns	Exchanges two columns.
	SwapRows	Exchanges two rows.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	Transpose	Modifies this matrix to be its transpose. This is like swapping rows with columns. http://en.wikipedia.org/wiki/Transpose
	Zero	Sets all values inside the matrix to zero.

	Name	Description
	Addition	Adds two matrices and returns a new sum matrix.
	Multiply	Multiplies two matrices and returns a new product matrix.
