function handleMATLAB

Hi all.

if a have a function:

x_out = f(x), where x is some vector.

How would i create a new function where a subset of the vector has been given as input:

x_out = f(x(3:4))

Thanks a lot

f34 = @(x) f(x(3:4));

Isn't this trivial?

f = @cos;
x = linspace(0, 2*pi, 100);
y = sin(x);
y2 = y - f(x);

or any other function instead of cos as long as it replies a vector with the same dimensions as the input.

This is how I would do it:

f = @(x) (x/4).*((x > 0) & (x < 1)) + (x/3).*(x >= 1);
t = linspace(-5, 5);
figure
plot(t, f(t))
grid
