WebIn physics, a continuous spectrum usually means a set of achievable values for some physical quantity (such as energy or wavelength), best described as an interval of real numbers. It is the opposite of a discrete spectrum, a set of achievable values that are discrete in the mathematical sense where there is a positive gap between each value. WebThis function is also useful for going from a continuous variable to a categorical variable. For example, cut could convert ages to groups of age ranges.
