Step response

Calculation of the response of strictly proper SISO systems by the convolution integral

Program for calculation of the response of strictly proper SISO systems
to arbitrary input by the convolution integral:

*/num = numerator polynomial coefficients of transfer function

*/den = denominator polynomial
coefficients of transfer function
(Coefficients of 'num' and 'den' are specified as a row vector, in
decreasing powers of 's')

*/t = row vector of time points (specified by the user)

*/u = vector of input values at the time points contained in t

*/y = calculated response
