I want to write a program where user should be able to enter equation function of 1 variable. such as sin(t)-2t , but this equation is used in further calculations but i can't make this because the type of it is string. how can i solve this problem or change the type of input data to make mathematical calculations ?

What do you mean by function? Is it simply asking for a numerical input? If so,
f=input('enter input num\n')

Hi, I would like user to input function i.e. x^2 + 3*y^3 and then ask user for the value of x and y and get the value of the function for x and y. I have been looking foor an advice on various sites but nothing has worked for me. I have MATLAB R2020b.

Use str2func. See bio lim's comment from November 28, 2016 for an example.
