MATLAB: How can I do this in mat lab

how can i type this equation in matlab x(t)= cos(πt)[u(t) − u(t − 1)] and h(t) = 1.5[u(t) − u(t − 1.5)] ???

Best Answer

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)')

t=0:0.001:20

% as you decrease the step size the graph becomes more and more acurate.%

x= J0(pi*t)(heaviside(t)-heaviside(t-1))

plot(t,x)

y=1.5*cos(pi*t).*(heaviside(t)-heaviside(t-1.5))

plot(t,y)

One way, using the exact equation you posted:

syms x t 
a = 4.2;                                        % Use Appropriate Value
u(x,t) = t+sin(x-a*t);
figure
fsurf(u, [- pi pi  0 1])

and another possibility:

x = linspace( ... );                            % Create Vector
t = linspace( ... );                            % Create Vector
[X,T] = ndgrid(x,t);
u = @(x,t) t+sin(x-a.*t);
figure
mesh(X, T, u(X,T))
grid on
