Defining variables inside of a function

t = 0:0.1:2; y(t) = cos(2*t); Array indices must be positive integers or logical values.

My problem here is that I want to have the variable "t" known inside the parentheses beside "y" as a regular written function in Matlab but I can't figure it out I tried searching for it online and found nothing.

Answer 1

syms y(t)
y(t) = cos(2*t)
t = 0:0.1:2; 
y=double(subs(y))

OR

y =@(t) cos(2*t) %Not sure which one you want but both gives the same results
y(t)

Thanks a lot this worked for me.

you’re welcome

There is also another way that I am not sure of, my teacher said (just a part of it) that I could define it by typing this y:( ) but the problem he didn't continue what I should be typing inside of the parentheses

[madhan ravi]

not sure what your teacher meant

t = 0:0.1:2;
y = cos(2*t);
