I have a very simple question that I can't seem to find the answer to. I have a defined equation, P, which has a function handle t. I want to define another function, cp, that takes the function P and multiplies its value by 3.75. So I want cp(5) = 3.75*205*5. I tried to make a function handle P for cp to say it is a function of P but it did not work.
P = @(t)205*t
cp = @(P)3.75*P

You can't multiply a number and a function handle.
You can multiply a number and the value you receive by evaluating a function handle.
P = @(t) 205*t
cp = @(t) 3.75*P(t)
cp(5)
