this is a MATLAB code problem please help

3. The Gramacy and Lee Function is given by the following: sin (10Tr) 2r + (r 1) (a) Create a function to evaluate the Gramacy and Lee function on a vector of r values. This is best done using an inline function! (b) Evaluate your function for the following x values, x --1:0.8:2.5. (c) Now interpolate the values of the function at the following r values, x--1:0.01:2.5 Perform this interpolation twice, once using linear interpolation and once using spline interpolation (d) Plot the original data as points, both interpolations as lines, and the evaluation of the actual function on x-1:0.01:2.5. 3.
