Matlab help...easy for some im sure

[rpeter]

I have to write program for Lagrange interpolation.

I have 5 (f(x)) values for a stock market share day....x values= 1-5 and have to use Lagrange to write a program to predict the 6th days stock price.

I’m a civil engineering student and this mat lab stuff goes well over my head so all advice is welcome:)
