How to plot a multiplication of two unit step functions (denoted by u(t)) ? Function I need the plot for is : F(t) = u(t) * u(10 – t)

Best Answer

u = @(t) double(t >= 0);
v = @(t) u(t).*u(10-t);
ezplot(v,[-10,20])

WTP?

syms u(t) x(t) h(t)
u(t)=piecewise(t>=0,1,0);
x(t)=cos(pi*t)*(u(t)-u(t-1));
h(t)=1.5*(u(t)-u(t-1.5));
%%plot
t=0:0.001:5;
plot(t,x(t),t,h(t));legend('x(t)','h(t)')

MATLAB: Find intersection point between u(t) = t^2(t-1) and u = 10.

Simply use the function you calculated:

>> t_sol = vpasolve(uSol == 10,t)
 
ans =
 
                                         2.5445115283879060011505370208062

 - 0.77225576419395300057526851040312 - 1.8258281475484665736721861577551i

I think you can withdraw the complex solutions and the result looks like in would work looking at the plot. Testing the solution:

 >> test_sol = uSol(t_sol(1))
 
test_sol =
 
10.0
