Hello,

I am getting too many input and output arguments error, I have tried to solve it but i am not able to understand the way to solve.

below is my fucntion

function [x_t,v_t] = Exercise_2_1_solve_equation_of_motion_analytically_func (mass,stiffness,damping,time,x_0,x_dot_0)
    %% 2.) Computing
    %% 2.) -Parameter calculation
    dampingcoefficient = damping/2*mass;              % Calculate damping coefficient
    angulareigenfrequency = sqrt(stiffness/mass);       % Calculate angular eigenfrequency
    %% 2.) -Calculation of the characteristic polynomial
    lambda = roots([1,2*dampingcoefficient,angulareigenfrequency^2]); %Calculate roots
    %% 2.) -Calculation of the constants
    k1 = (x_dot_0-lambda(2)*x_0)/(lambda(1)-lambda(2));           % Calculation of the constant 1
    k2 = (lambda(1)*x_0-x_dot_0)/(lambda(1)-lambda(2));           % Calculation of the constant 2
    %% 2.) -Calculation of the solution
    x_t_h = k1*exp(lambda(1)*time)+k2*exp(lambda(2)*time);                         
    v_t_h = k1*lambda(1)*exp(lambda(1)*time)+k2*lambda(2)*exp(lambda(2)*time);
    x_t = real(x_t_h);                                                  % Make sure only real part is considered
    v_t = real(v_t_h);                                                  % Make sure only real part is considered
end

And the calling script is as below :

%%To solve equation of motion analytically
%% Parameter definition
mass                       = 750;                 % Mass of the body [kg]
stiffness                  = 50000;               % Stiffness Coefficient of spring [N/m]
damping                    = 1000;                % Damping coefficient of damper [Ns/m]
time                       = 0:0.01:1;            % Time [s]
x_0                        = 0.01;                % Initial Condition displacement
x_dot_0                    = 0;                   % Initial Condition velocity
%% Call the function
[x_t,v_t] = Exercise_2_1_solve_equation_of_motion_analytically_func(mass,stiffness,damping,time,x_0,x_dot_0);
