Method Detail

get

public double get(int row,
         int col)

Description copied from interface: Matrix64F

Returns the value of value of the specified matrix element.

Specified by:

get in interface Matrix64F

Parameters:

row - Matrix element's row index..

col - Matrix element's column index.

Returns:

The specified element's value.

unsafe_get

public double unsafe_get(int row,
                int col)

Description copied from interface: Matrix64F

Same as Matrix64F.get(int, int) but does not perform bounds check on input parameters. This results in about a 25% speed increase but potentially sacrifices stability and makes it more difficult to track down simple errors. It is not recommended that this function be used, except in highly optimized code where the bounds are implicitly being checked.

Specified by:

unsafe_get in interface Matrix64F

Parameters:

row - Matrix element's row index..

col - Matrix element's column index.

Returns:

The specified element's value.

set

public void set(int row,
       int col,
       double val)

Description copied from interface: Matrix64F

Sets the value of the specified matrix element.

Specified by:

set in interface Matrix64F

Parameters:

row - Matrix element's row index..

col - Matrix element's column index.

val - The element's new value.

unsafe_set

public void unsafe_set(int row,
              int col,
              double val)

Description copied from interface: Matrix64F

Same as Matrix64F.set(int, int, double) but does not perform bounds check on input parameters. This results in about a 25% speed increase but potentially sacrifices stability and makes it more difficult to track down simple errors. It is not recommended that this function be used, except in highly optimized code where the bounds are implicitly being checked.

Specified by:

unsafe_set in interface Matrix64F

Parameters:

row - Matrix element's row index..

col - Matrix element's column index.

val - The element's new value.

getNumRows

public int getNumRows()

Description copied from interface: Matrix64F

Returns the number of rows in this matrix.

Specified by:

getNumRows in interface Matrix64F

Returns:

Number of rows.

getNumCols

public int getNumCols()

Description copied from interface: Matrix64F

Returns the number of columns in this matrix.

Specified by:

getNumCols in interface Matrix64F

Returns:

Number of columns.

getNumElements

public int getNumElements()

Description copied from interface: Matrix64F

Returns the number of elements in this matrix, which is the number of rows times the number of columns.

Specified by:

getNumElements in interface Matrix64F

Returns:

Number of elements in this matrix.

copy

public <T extends Matrix64F> T copy()

Specified by:

copy in interface Matrix64F

print

public void print()

Specified by:

print in interface Matrix64F
