Today – Numerical Errors, Midterm Review
Q1) You are performing a Golden Section search in order to maximize a function f. If on the first
iteration, x1 = -2.73 and x0 = 6.73, how many iterations would be required to solve Emax to less than
0.001?
a) 14
b) 15
c) 16
d) Less than 14
e) More than 16
Midterm Review
MATLAB:
Assigning values to variable, especially vectors
- built in functions – sin, cos, log
- element by element operations
- control statements – if, else, while, for
- logic a < 3 || b = -3 etc
- comments – MAKE SURE TO INCLUDE 3 LINE COMMENT AT TOP OF FUNCTION – INPUT,
OUTPUT, DESCRIPTION
- anonymous functions
- file functions, void functions in script files
- plot, fplot
- roots, fminbnd, - input -prompt to type
-polyval, polyder, polyint
- fprintf - %d, %f
MANUAL:
- root finding - incremental, bisection, false position, Newton- Raphson, Secant, Modified secant
-optimization – Golden Section Method
-DO SNAP QUIZZES
