Using Values from Tabulated Data

Hello,

Let's say there is a function called A(t). A(t) is not a defined function, but there are specific values of A for given values of t.

Ex:

if t=1, A=78

t=2.5, A=80

etc.

For reference, there are about 20 values of t that are given with 20 values of A

How can I code this in matlab so that, in I enter A(1) it returns a value fof 78?

Thanks!

t = [1 2.5 3.6 4];
A = [78 80 85 96];

Afun=@(tq)interp1(t,A,tq);

Afun(1)

ans = 78

Afun(2)

ans = 79.3333

Afun(2.5)

ans = 80
