Matrix Methods

The Matrix type exposes the following members.

Methods
NameDescription
BackSolve
Solves M*x=b where M is upper triangular with a unit diagonal and b is a column of values.
BackSolvePoints
Solves M*x=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 ObjectFinalize.)
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 ObjectGetHashCode.)
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 M*X=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 M*X=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.

Zero
Sets all values inside the matrix to zero.
