How to write a script for the following

hi everyone, i was just introduced to MatLab and want to how to write a script for the question bellow

A certain mechanical system has the process function f(x)=5t^4-4^t-t^2-t+5. Write a MATLab script that will be able to evaluate the state of the system at the point t=3

[Walter Roberson]

hint: matlab has no implied multiplication. 3y would be written 3*y

Your function f takes an input of x but the definition of f does not involve x at all, just t and some scalars. Why does it say x???

Or with other words: define it as f(t).

Search for "anonymous functions" in the documentations. The command docsearch will be useful.

f = @(t)5*t.^4-4.^t-t.^2-t+5;
f(3)

ans = 334
