Method Detail

printNonZero

void printNonZero()

Prints to standard out the non-zero elements only.

reshape

void reshape(int numRows,
             int numCols,
             int nz_length)

Reshapes the matrix so that it can store a matrix with the specified dimensions and the number of non-zero elements

Parameters:

numRows - number of rows

numCols - number of columns

nz_length - Number of non-zero elements

shrinkArrays

void shrinkArrays()

Reduces the size of internal data structures to their minimal size. No information is lost bu

remove

void remove(int row,
            int col)

If the specified element is non-zero it is removed from the structure

Parameters:

row - the row

col - the column

zero

void zero()

Sets all elements to zero by removing the sparse graph
