f(t)=(2-e-2t)u(t)的MATLAB程序怎么写

Question

如题所述

Answer 1

t=[0:0.01:10];
x=(2-exp(-2*t));
plot(t,x);
xlabel('t');
ylabel('x(t)');
title('x(t)=(2-exp(-2*t)');

Answer 2

t=-2:0.02:2;
f1=(2-exp(-2*t)).*heaviside(t);
plot(t,f1);
xlabel('t');ylabel('(2-e^(-2t))u(t)');
title('(2-e^(-2t))u(t)');

Answer 3

楼上错误，同求答案

Answer 4

t=0:10;
f=(2-e.*(12*t))*u;
