Matrix Class |
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.
Inheritance HierarchyNamespace: Rhino.Geometry
Assembly: RhinoCommon (in RhinoCommon.dll)
SyntaxThe Matrix type exposes the following members.
Constructors| 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.
|
Properties| 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 indices.
|
| RowCount |
Gets the amount of rows.
|
Methods| Name | Description | |
|---|---|---|
| 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. http://en.wikipedia.org/wiki/Transpose |
| Zero |
Sets all values inside the matrix to zero.
|
Operators| Name | Description | |
|---|---|---|
  | Addition |
Adds two matrices and returns a new sum matrix.
|
| Multiply |
Multiplies two matrices and returns a new product matrix.
