Constructor Detail

MutableFloatMatrix

protected MutableFloatMatrix(U unit)

Construct a new MutableFloatMatrix.

Parameters:

unit - U; the unit of the new MutableFloatMatrix

Method Detail

immutable

public abstract FloatMatrix<U> immutable()

Make (immutable) FloatMatrix equivalent for any type of MutableFloatMatrix.

Returns:

FloatMatrix<U>; immutable version of this FloatMatrix

checkCopyOnWrite

protected final void checkCopyOnWrite()

Check the copyOnWrite flag and, if it is set, make a deep copy of the data and clear the flag.

setSI

public final void setSI(int row,
                        int column,
                        float valueSI)
                 throws ValueException

Replace the value at row, column by the supplied value which is expressed in the standard SI unit.

Specified by:

setSI in interface WriteFloatMatrixFunctions<U extends Unit<U>>

Parameters:

row - int; row of the value to replace

column - int; column of the value to replace

valueSI - float; the value to store (expressed in the standard SI unit)

Throws:

ValueException - when row or column out of range (row < 0 or row >= rows() or column < 0 or column >= columns())

set

public final void set(int row,
                      int column,
                      FloatScalar<U> value)
               throws ValueException

Replace the value at row, column by the supplied value which is in a compatible unit.

Specified by:

set in interface WriteFloatMatrixFunctions<U extends Unit<U>>

Parameters:

row - int; row of the value to replace

column - int; column of the value to replace

value - FloatScalar<U>; the strongly typed value to store

Throws:

ValueException - when row or column out of range (row < 0 or row >= rows() or column < 0 or column >= columns())

setInUnit

public final void setInUnit(int row,
                            int column,
                            float value,
                            U valueUnit)
                     throws ValueException

Replace the value at row, column by the supplied value which is expressed in a supplied (compatible) unit.

Specified by:

setInUnit in interface WriteFloatMatrixFunctions<U extends Unit<U>>

Parameters:

row - int; row of the value to replace

column - int; column of the value to replace

value - float; the value to store (which is expressed in valueUnit)

valueUnit - U; unit of the supplied value

Throws:

ValueException - when row or column out of range (row < 0 or row >= rows() or column < 0 or column >= columns())

assign

public final void assign(FloatFunction floatFunction)

Execute a function on a cell by cell basis. Note: because many functions have to act on zero cells or can generate cells with a zero value, the functions have to be applied on a dense dataset which has to be transformed back to a dense dataset if necessary.

Parameters:

floatFunction - the function to apply

incrementByImpl

protected final MutableFloatMatrix<U> incrementByImpl(FloatMatrix.Rel<U> rel)
                                               throws ValueException

Increment the values in this MutableFloatMatrix by the corresponding values in a Relative FloatMatrix.
Only Relative values are allowed; adding an Absolute value to an Absolute value is not allowed. Adding an Absolute value to an existing Relative value would require the result to become Absolute, which is a type change that is impossible. For that operation use a static method.

Parameters:

rel - FloatMatrix.Rel<U>; the Relative FloatMatrix

Returns:

MutableFloatMatrix<U>; this modified MutableFloatMatrix

Throws:

ValueException - when the matrices do not have the same size

decrementByImpl

protected final MutableFloatMatrix<U> decrementByImpl(FloatMatrix.Rel<U> rel)
                                               throws ValueException

Decrement the corresponding values of this Relative FloatMatrix from the values of this MutableFloatMatrix.
Only Relative values are allowed; subtracting an Absolute value from a Relative value is not allowed. Subtracting an Absolute value from an existing Absolute value would require the result to become Relative, which is a type change that is impossible. For that operation use a static method.

Parameters:

rel - FloatMatrix.Rel<U>; the Relative FloatMatrix

Returns:

MutableFloatMatrix<U>; this modified MutableFloatMatrix

Throws:

ValueException - when the matrices do not have the same size

scaleValueByValue

protected final void scaleValueByValue(FloatMatrix<?> factor)
                                throws ValueException

Scale the values in this MutableFloatMatrix by the corresponding values in a FloatMatrix.

Parameters:

factor - FloatMatrix<?>; contains the values by which to scale the corresponding values in this MutableFloatMatrix

Throws:

ValueException - when the matrices do not have the same size

scaleValueByValue

protected final MutableFloatMatrix<U> scaleValueByValue(float[][] factor)
                                                 throws ValueException

Scale the values in this MutableFloatMatrix by the corresponding values in a float array.

Parameters:

factor - float[][]; contains the values by which to scale the corresponding values in this MutableFloatMatrix

Returns:

MutableFloatMatrix<U>; this modified MutableFloatMatrix

Throws:

ValueException - when the matrix and the array do not have the same size

normalize

public final void normalize()
                     throws ValueException

Normalize the matrix, i.e. scale the values to make the sum equal to 1.

Specified by:

normalize in interface WriteFloatMatrixFunctions<U extends Unit<U>>

Throws:

ValueException - when the sum of the values is zero and normalization is not possible
