BoundedRealVector
public BoundedRealVector(double[] x, double min, double max)
Initializes the vector to the specified values, subject to the given bounds [min, max].- Parameters:
x
- The initial values for the vector. Any values that are less than min will instead be set to min. Any values that are greater than max will instead be set to max.min
- The minimum allowed value for each integer.max
- The maximum allowed value for each integer.- Throws:
IllegalArgumentException
- if min > max
-
BoundedRealVector
public BoundedRealVector(BoundedRealVector other)
Copies a BoundedRealVector.- Parameters:
other
- The other BoundedRealVector

Method Detail

set
public final void set(int i, double value)
Sets a parameter to a specified value, subject to the lower and upper bounds for this function input. If the specified new value is less than the min, then the function input is set to the min. If the specified new value is greater than the max, then the function input is set to the max. Otherwise, the function input is set to the specified value.- Specified by:
set
in interfaceRealValued
- Overrides:
set
in classRealVector
- Parameters:
i
- The input to set.value
- The new value for the i-th function input.- Throws:
ArrayIndexOutOfBoundsException
- if i < 0 or i ≥ length().
-
sameBounds
public final boolean sameBounds(BoundedRealVector other)
Checks if the bounds of this BoundedRealVector are the same as those of another.- Parameters:
other
- The other vector.- Returns:
- true if the vectors have the same bounds and false otherwise
-
copy
public BoundedRealVector copy()
Creates an identical copy of this object.- Specified by:
copy
in interfaceCopyable<RealVector>
- Overrides:
copy
in classRealVector
- Returns:
- an identical copy of this object
-
equals
public boolean equals(Object other)
Indicates whether some other object is "equal to" this one. To be equal, the other object must be of the same runtime type and contain the same values and bounds.- Overrides:
equals
in classRealVector
- Parameters:
other
- The other object to compare.- Returns:
- true if other is not null, is of the same runtime type as this, and contains the same values and bounds.
-
hashCode
public int hashCode()
Returns a hash code value.- Overrides:
hashCode
in classRealVector
- Returns:
- a hash code value
