I want to enter a mathematical function as an argument to a function

Hello, to be more precise: I want to call in my program a function that I have created and that allows to display the plot of a mathematical function, so I want to enter in argument of this function a mathematical expression that can be for example "sin(t) or 4*t+9". Knowing that the interval "t" is defined inside the function.
My problem is the following, when I launch the program it says to me that it does not know "t", logic since at the moment or the program reads it it is not yet defined.
How to solve this problem?
main program
plot_compare(sin(t) , 5 ,20);
secondary program
function plot_compare(f,N,M)
t = [];
S_N = [];
t = linspace(-pi ,pi ,M);
b = linspace (0,10,N);
S_N = sinesum(t,b);
plot(t,f,t,S_N);
end
