# SP4E Homeworks
Students:  
* Lars B.
* Bertil T.

In this repository, we will keep all homeworks for SP4E

## Homework 1
See folder named *hw1-conjugate-gradient*.

#### Requirements
* Numpy
* Scipy
* Matplotlib
* Argparse

The code as been tested with Python 3.

#### Usage
Run the *main_minimize.py* with the following arguments:
* -A < matrix elements in row major order >
* -b < vector elements >
* -x0 < initial guess elements >
* -method < CG-scipy or CG-ours >
* -plot < True or False >

#### Example

The following command will run the program with the coefficients given in Exercise 1:  

python main_minimize.py -A 8 0 2 6 -b 0 1 -x0 4 4 -method CG-scipy -plot True   

NB: Note the scaling of S(x) with 1/2 between Ex 1 and 2.
