Jagged |
JaggedArrayMatrix is a matrix implementation that is relatively easy to extend to the bottom, i.e. to append rows.
It is horizontal oriented, i.e. the storage is as a number of horizontal vectors. Furthermore, as a compromise, it provides fully
access to its underlying jagged array.

SyntaxC#
public class JaggedArrayMatrix : IMatrix<double>, IROMatrix<double>, IBottomExtensibleMatrix<double>
The JaggedArrayMatrix type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | JaggedArrayMatrix(Double) | Uses an already existing array for the matrix data. |
| JaggedArrayMatrix(Int32, Int32) | Sets up an empty matrix with dimension(row,cols). |
| JaggedArrayMatrix(Double, Int32, Int32) | Uses an already existing array for the matrix data. |
Properties| Name | Description | |
|---|---|---|
 | Array | Provides direct access to the underlying jagged array. JaggedArrayMath can then be used to speed up computations. |
| ColumnCount | Number of columns of the matrix. |
| Item | Element accessor. Accesses the element [row, col] of the matrix. |
| RowCount | Number of Rows of the matrix. |
Methods| Name | Description | |
|---|---|---|
| AppendBottom | Appends the matrix a at the bottom of this matrix. Either this matrix must be empty (dimensions (0,0)) or the matrix to append must have the same number of columns than this matrix. |
| Clear | Clears the content of the matrix. |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| SetDimension | Set up the dimensions of the matrix. Discards the old content and reset the matrix with the new dimensions. All elements become zero. |
| ToString |
Represents the content of the matrix as a string.
(Overrides ObjectToString) |
Extension Methods| Name | Description | |
|---|---|---|
 | Any |
Determines whether any element of the provided matrix a fulfills the given predicate.
