Trying to plot a function with changing variables.

Below is my code and I am trying to plot time versus x. Every time i do plot(mbk(1,40)) it gives my the error too many outputs. Please help!!!

function mbk(m,k)

%-----variables--------- b=linspace(0,15,6); t=linspace(0,3,100);

%-----derived constants------ wn=sqrt(k/m); gamma= b/(2*m*wn); tau=wn*t;

%-----------------formulas----------- if (b==0) %Solve for x and plot t x Ty x=6*cos(tau)+ (3/wn)* sin(tau);

elseif b>0 %Solve for x and plot t x Ty if gamma==1 x= 6*exp(-tau)+ 3*tau*exp(-tau); hold on elseif gamma < 1 %Solve for x and plot t x Ty x = exp(-gamma*tau)*(6*cos(sqrt(1-gamma^2)*tau))... +((6*gamma-3)/sqrt(1-gamma^2))*sin(sqrt(1-gamma^2)*tau);

    else gamma > 1;
        x = exp(-gamma*tau)*(6*cos(sqrt(gamma^2-1)*tau))...
            +((6*gamma-3)/sqrt(gamma^2-1))*sin(sqrt(gamma^2-1)*tau);

    end

end

You are not returning any variables from the function mbk. Try: function [name_var_1,name_var_2] = mbk(m,k)
