Class FMatrixIterator

All Implemented Interfaces:

@Generated("") public class FMatrixIterator extends Object implements Iterator<Float>
This is a matrix iterator for traversing through a submatrix. For speed it is recommended that you directly access the elements in the matrix, but there are some situations where this can be a better design.
  • Constructor Details

    • FMatrixIterator

      public FMatrixIterator(FMatrixD1 a, boolean rowMajor, int minRow, int minCol, int maxRow, int maxCol)
      Creates a new iterator for traversing through a submatrix inside this matrix. It can be traversed by row or by column. Range of elements is inclusive, e.g. minRow = 0 and maxRow = 1 will include rows 0 and 1. The iteration starts at (minRow,minCol) and ends at (maxRow,maxCol)
      a - the matrix it is iterating through
      rowMajor - true means it will traverse through the submatrix by row first, false by columns.
      minRow - first row it will start at.
      minCol - first column it will start at.
      maxRow - last row it will stop at.
      maxCol - last column it will stop at.
