Homework 6 - Due Friday, March 25 1) Create a function that parses the following files: a) mat33 = """ 1.0 2.0 3.0 -2.0 0.0 1.0 1.0 1.1 1.2 """ # output a matrix def parse_mat(s): mat = [] # build a list of lists ... return array(mat) # make into an array
 * 1) example function structure

b) csv = """ 0.0, 300.0, 44.5 1.5, 299.5, 44.0 3.0, 299.8, 44.2 4.5, 301.0, 43.9 """ # output a list of strings and a matrix
 * 1) time temperature sea_level

c) name_val = """ seed = 1553 name = "test name" trials = 10 tolerance = 1e-8 """ # output a dictionary

d) group_data = """ [Group 1] 1 2 3 4 5 6

[Group 2] 4 5 11 14 1

[Group 3] 7 8 9 10 11 """ # output a dictionary of [int]

2) Complete this function by adding a for loop to fill each  element of a vector with a function (g(i)):  from numpy import *  def vec_from_func(n, g): # int -> (int -> float) -> array    x = zeros(n, float)    for ...    return x

# example call def square_x(x): # int -> float return 1.0*x*x

g_arr = vec_from_func(10, square_x)

3) Complete this function by adding a nested for-loop to fill  each element of a matrix with a function, u(i,j):   from numpy import *   def mat_from_func(n,m, g): # int -> int -> (int -> int -> float) -> array   M = zeros((n,m), float)   for ...     for ...   return M
