MATLAB PROJECT (ONLY USE MATLAB CODE)

Given in the data file (info.dat), where the first column is the "y" values and the second column is the "x" values .

info.dat

+4.60000E-01 +2.39944E-08 +5.00000E-01 +5.47030E-08 +9.70000E-01 +1.15987E-03 +1.21200E+00 +1.90309E-01 +1.24300E+00 +4.21568E-01

Write a MATLAB code to import the associated data using the given dat file and write the variable y in terms of variable x and find its value using

a) Least squares approximation

b) Lagrange interpolation

(Hint: Remember to convert the given exponential function to linear form when using these methods. )

( e = euler number = 2.7182 )

x = b * (e)axy x = b * (e)axy
