Trigonometric Integrals

random_band is the main program and it outputs a test signal which has a constant level. The instanatenous frequency varies randomly within the specified Nth octave band range.The program outputs three plots: time record of the instantaneous frequency, time record of the instantaneous level, and...

The m-file overlap_integral.m calculates the vibrational overlap integral between two nuclear wavefunctions using the formalism developed by Sharp and Rosenstock (J. Chem. Phys., 41:3453, 1964). This function requires the MATLAB Symbolic Toolbox in order to run correctly. The m-file...
