Class DenseColumnFloatMatrix2D

  • All Implemented Interfaces:
    Serializable, Cloneable


    public class DenseColumnFloatMatrix2Dextends FloatMatrix2D
    Dense 2-d matrix holding float elements. First see the package summary and javadoc tree view to get the broad picture.

    Implementation:

    Internally holds one single contigous one-dimensional array, addressed in column major. Note that this implementation is not synchronized.

    Time complexity:

    O(1) (i.e. constant time) for the basic operations get, getQuick, set, setQuick and size,

    Cells are internally addressed in column-major. Applications demanding utmost speed can exploit this fact. Setting/getting values in a loop column-by-column is quicker than row-by-row. Thus

     for (int column = 0; column < columns; column++) {     for (int row = 0; row < rows; row++) {         matrix.setQuick(row, column, someValue);     } }  
    is quicker than
     for (int row = 0; row < rows; row++) {     for (int column = 0; column < columns; column++) {         matrix.setQuick(row, column, someValue);     } }
