DoubleArray()
create with default length |
|
DoubleArray(double[] dat)
copy initial data from another double[]. |
|
DoubleArray(DoubleArray dat)
copy initial data from another DoubleArray (non-null). do not use the above constructor in this case, as it would use all values, not just the used length (count); again: values are *copied* |
|
DoubleArray(int len)
create with initial buffer length |
