WebDescription: The period character separates the integral and fractional parts of a number, such as 3.1415. MATLAB operators that contain a period always work element-wise. The period character also enables you to access the fields in a structure, as well as the properties and methods of an object. http://www-classes.usc.edu/engr/ce/526/FFT5.pdf
