Method Details

zero

public void zero()

Description copied from interface: Matrix

Sets all values inside the matrix to zero

Specified by:

zero in interface Matrix

setTo

public void setTo(float a11,
 float a12,
 float a13,
 float a14,
 float a21,
 float a22,
 float a23,
 float a24,
 float a31,

 float a44)

setTo

public void setTo(int offset,
 float[] a)

get

public float get(int row,
 int col)

Description copied from interface: FMatrix

Returns the value of value of the specified matrix element.

Specified by:

get in interface FMatrix

Parameters:

row - Matrix element's row index..

col - Matrix element's column index.

Returns:

The specified element's value.

unsafe_get

public float unsafe_get(int row,
 int col)

Description copied from interface: FMatrix

Same as FMatrix.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 FMatrix

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,
 float val)

Description copied from interface: FMatrix

Sets the value of the specified matrix element.

Specified by:

set in interface FMatrix

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,
 float val)

Description copied from interface: FMatrix

Same as Matrix.setTo(org.ejml.data.Matrix) 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 FMatrix

Parameters:

row - Matrix element's row index..

col - Matrix element's column index.

val - The element's new value.

setTo

public void setTo(Matrix original)

Description copied from interface: Matrix

Sets this matrix to be identical to the 'original' matrix passed in.

Specified by:

setTo in interface Matrix

getNumRows

public int getNumRows()

Description copied from interface: Matrix

Returns the number of rows in this matrix.

Specified by:

getNumRows in interface Matrix

Returns:

Returns the number of columns in this matrix.

Specified by:

getNumCols in interface Matrix

getNumElements

public int getNumElements()

Description copied from interface: FMatrix

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

Specified by:

getNumElements in interface FMatrix

Returns:

Number of elements in this matrix.

copy

public <T extends Matrix> T copy()

Description copied from interface: Matrix

Creates an exact copy of the matrix

Specified by:

print

public void print()

Description copied from interface: Matrix

Prints the matrix to standard out using standard formatting. This is the same as calling print("%e")

Specified by:

print in interface Matrix

print

public void print(String format)

Description copied from interface: Matrix

Prints the matrix to standard out with the specified formatting.

Specified by:

print in interface Matrix

Parameters:

format - printf style formatting for a float. E.g. "%f"
