This program calculates a transfer function for two selected degreesoffreedom in a system based on the mode shapes, natural frequencies, and damping ratios. It also calculates the applied force for a single given displacement, velocity, or acceleration.  transfer_find_force.m 
This program calculates a
response time history from an input time history and a transfer function where the transfer function is a complex Fourier transform.
