Package cern.colt.matrix
Class ObjectFactory1D
java.lang.Object
cern.colt.PersistentObject
cern.colt.matrix.ObjectFactory1D
- All Implemented Interfaces:
Serializable
,Cloneable
Factory for convenient construction of 1-d matrices holding Object cells.
Use idioms like ObjectFactory1D.dense.make(1000) to construct dense matrices,
ObjectFactory1D.sparse.make(1000) to construct sparse matrices.
If the factory is used frequently it might be useful to streamline the notation.
For example by aliasing:
ObjectFactory1D F = ObjectFactory1D.dense; F.make(1000); ... |

Method Details
-
append
C = A||B; Constructs a new matrix which is the concatenation of two other matrices. Example: 0 1 append 3 4 --> 0 1 3 4. -
make
Constructs a matrix which is the concatenation of all given parts. Cells are copied. -
make
Constructs a matrix with the given cell values. The values are copied. So subsequent changes in values are not reflected in the matrix, and vice-versa.- Parameters:
values
- The values to be filled into the new matrix.
-
make
Constructs a matrix with the given shape, each cell initialized with zero. -
make
Constructs a matrix with the given shape, each cell initialized with the given value. -
make
Constructs a matrix from the values of the given list. The values are copied. So subsequent changes in values are not reflected in the matrix, and vice-versa.- Parameters:
values
- The values to be filled into the new matrix.- Returns:
- a new matrix.
-
repeat
C = A||A||..||A; Constructs a new matrix which is concatenated repeat times. Example:0 1 repeat(3) --> 0 1 0 1 0 1
-
toList
Constructs a list from the given matrix. The values are copied. So subsequent changes in values are not reflected in the list, and vice-versa.- Parameters:
values
- The values to be filled into the new list.- Returns:
- a new list.
