Overload List
| Get | Returns a matrix containing only the rows in the specified subset. |
| Get | Returns a matrix that contains only the specified rows of the current matrix. |
| Get | Returns a new matrix that contains only the rows in the specified sequence. |
GetRows<R>(IEnumerable<R>)
Returns a new matrix that contains only the rows
in the specified sequence.
public Matrix<T> GetRows<R>(
IEnumerable<R> keys
)
Parameters
- keys IEnumerable<R>
- A sequence of keys of the rows to return.
Type Parameters
- R
