Here is what i need to do. I have to input the interval, number of interpolation points, and 4 functions. I need to then create chebyshev points, and iterpolate the functions. What I need help with is how do I create a function from a user input so I can evaluate at the two different intervals.
example on function is exp(-x) f = input('enter function: ') this is what i have, but what i want is to make this a fucntion
f = inline@(input('enter function: ')) but this wont work. what am i doing wrong?

Hi,
you should try to use inputdlg , which creates a basic gui easy to use and you can specify default values (or string exp(x) ).
this way, in one gui, on ask for the interval, number of interpolation points, and 4 functions.
