public abstract void reshape(int numRows,
int numCols,
boolean saveValues)
Changes the number of rows and columns in the matrix, allowing its size to grow or shrink. If the saveValues flag is set to true, then the previous values will be maintained, but reassigned to new elements in a row-major ordering. If saveValues is false values will only be maintained when the requested size is less than or equal to the internal array size. The primary use for this function is to encourage data reuse and avoid unnecessarily declaring and initialization of new memory.
Examples:
[ 1 2 ; 3 4 ] -> reshape( 2 , 3 , true ) = [ 1 2 3 ; 4 0 0 ]
[ 1 2 ; 3 4 ] -> reshape( 1 , 2 , true ) = [ 1 2 ]
[ 1 2 ; 3 4 ] -> reshape( 1 , 2 , false ) = [ 1 2 ]
[ 1 2 ; 3 4 ] -> reshape( 2 , 3 , false ) = [ 0 0 0 ; 0 0 0 ]
numRows - The new number of rows in the matrix.numCols - The new number of columns in the matrix.saveValues - If true then the value of each element will be save using a row-major reordering. Typically this should be false.public void reshape(int numRows,
int numCols)
numRows - The new number of rows in the matrix.numCols - The new number of columns in the matrix.public MatrixIterator iterator(boolean rowMajor, int minRow, int minCol, int maxRow, int maxCol)
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.public int getNumRows()
