Question number 01:

Matlab code:

function [ yt, Tau, Tr, Tp, Mp ] = Specification(tspan, y0, wn, zeta, theta, N, str)

%Specification Summary of this function goes here

% Detailed explanation goes here



if( nargin < 7 | nargin > 7)

error ('Too many input arguments or too less input arguments');

elseif ( nargin == 7 )

N = 100;

if (str=='y')

if ( tspan(1)<0 | tspan(2)< tspan(1))

error('inital time should be greater than equal to zero and final time should be greater than or equal to initial time');

end

end

else

end

t = linspace (tspan(1),tspan(2),N);

yt = (y0./(sqrt(1-(zeta*zeta)).* exp((-zeta*wn*t).* sin(wn* sqrt(1-(zeta*zeta*t)+ theta )))));

Tau = 1/(zeta * wn);

Tr = ...
