Question

This is a portion of my code:-

t = -4 : 0.01  :4;
f = inline('(-1.5*t+1) .* ((t>-3)&(t<0)) + (1.5*t+1) .* ((t>0)&(t<3))');
plot(t, f(t), 'r','linewidth', 2);
grid on;

Here I am getting the value of f(0) = 0

>> f(0)

ans =

     0

I want to plot the function with f(0) = 3
For that I tried this

f = inline('(-1.5*t) .* ((t>-3)&(t<0)) + (3) .* (t = 0) +(t) .* ((t>0)&(t<3))');

But I am getting an error when I use the same plot command.

plot(t, f(t), 'r','linewidth', 2);

Can anybody suggest the correct method.?

Answer 1

The error is because you have (t = 0) but you probably wanted (t == 0)

i.e.

f = inline('(-1.5*t) .* ((t>-3)&(t<0)) + (3) .* (t == 0) +(t) .* ((t>0)&(t<3))');

now f(0) gives 3
