I have tried to create a function x(t/2) using handle like this:

x = @(t/2);

however, this gives an error. I can also not write it in terms of another variable like this

y = t/2; x = @(y);

since this also gives an error and says that t was not declared. I can not use syms to declare t since it is not allowed in the question. Can someone please help me with this?

You must write it as a function of t. Only when you valuate the function handle, you can insert t/2.

x = @(t) t.^2;

t = linspace(0,1,100);

y = x(t/2);

plot(t,y)

"a function x(t/2)" is not clear. What do you want as output of the function?

在 MATLAB Online 中打开

Try something like this —

x = @(t) (t/2);
t = 42;
y = x(t/2)
y = 10.5000

See the documentation section on Anonymous Funcitons for details.
