Here is my entire code(average is not working yet). The response I got from the professor is that I have to create a DRY solution replacing the five display_functions with a single get_array function you call five times like common_array = get_array(plant_xml, "COMMON") etc. from urllib.request import urlopenfrom xml.etree.ElementTree import parse def read_data(data_file): plant_url = urlopen(data_file) plant_xml = parse(plant_url) return plant_xml def display_common_items(plant_xml): plant_root = plant_xml.getroot() common_array = [] for item in plant_root.findall("PLANT"): common_array.append(item.find("COMMON").text) return common_array def display_botanical_items(plant_xml): plant_root = plant_xml.getroot() botanical_array = [] for item in plant_root.findall("PLANT"): botanical_array.append(item.find("BOTANICAL").text) return botanical_array def display_zone_items(plant_xml): plant_root = plant_xml.getroot() zone_array = []…
Please written by computer source const int ROW_SIZE = 10; const int COLUMN_SIZE = 10; int myMatrix[ROW_SIZE][COLUMN_SIZE]; Note that these constants will be in main and not in the scope of any other function. That is, you must design your functions to have parameters to receive the dimensions. Write a function called initialize that receives a 2D array and initializes the array with random values between 0 and 99. Add a message that confirms the successful creation of the matrix. Call this function in main to initialize myMatrix. Write a function called display that receives a 2D array and displays the elements of the array in a tabular format. Arrange the method to display row and column numbers. Row indices displayed on the left and column indices displayed at the top. Call this function in main to print myMatrix. Write a function called sumEven that receives a 2D array and returns the sum of all the even elements. Call this function in main to calculate and display this value for…
If a and b are two non-empty numerical row vectors (of the same length L) present in Matlab Workspace, what command would you use to create a new 2 x L matrix, called d, that is a combination of a and b (a elements are in the first row and elements of b are in the second row)? d = transpose(a, b) d = a _ b d = [a; b] d = a .* (1/b)
Which of the following code segments will use vectorisation to reduce the time taken to calculate the sum of two NumPy arrays: A and B? (Select ALL that apply) 1. ) C = np.empty(A.size) for index in range(A.size): C[index] = A[index] + B[index] 2.) A.tolist()+B.tolist() 3.) np.sum([A, B]) 4.) A+B

Assume that a two-dimensional array of doublewords has three logical rows and four logical columns. If ESI is used as the row index, what value is added to ESI to go from one row to the next?
Create a client that produces partly sorted arrays with the following features: 95% of the data are sorted, while 5% are random values.All items that are within 10 places of their array positionSorted, with the exception of 5% of the items that were distributed at random across the array. Create and test ideas about how such input will affect how well the algorithms in this part function.
Creates a 15 element vector in pandas Plot the vector Remove 5 values from the vector Replot the vector Interpolate the missing values in the vector Replot the vector Copy the plots into Word and write a few sentences explaining the results Creates a 4x8 array in pandas that consists of 4 variables with 8 data points for each Adds axis labels to the 4x8 array Use the describe command on the 4x8 array Plot the 4x8 array Using the attached random_picker.py program select 6 locations to replace with NA in your 4x8 array (Run the picker program seperatly and then hard code the deletions) Use the describe command on the 4x8 array Using the interpolate method, fill in the missing data. If you still have missing data use the appropriate fillna method (ffill/bfill) to fix Describe the 4x8 array Plot the 4x8 array Copy the results of the describe command and the plots to the Word file and write up the results
Question 4: Getting the diagonal of a 2D array Definition In this question we define a functon called getDiagonal that takes a two dimensional array as a parameter and returns a vector representing the diagonal of that vector. Testing This function can be tested using a driver file. A driver file containing three test cases is: A=[1 2 3; 4 5 6; 7 8 9]; disp(getDiagonal(A)); B=[1 2 3; 4 5 6]; disp(getDiagonal(B)); C=[1 2; 3 4; 5 6]; disp(getDiagonal(C)); The output of this driver would be: 1 5 9 1 5 1 4 Write two more test cases for this driver. Coding If you are sharing a computer, swap a new group member to the terminal. Write a MATLAB function that implements the definition above using a for-loop.
Create a 3-by-3 matrix: A = [1 2 3;4 5 6;7 8 10] (a)Extract a submatrix B consisting of rows 1 and 3 and columns 1 and 2 of the matrix A (b)Interchange rows 1 and 3 of A and put it in a variable C. Hint: use the vector of row indices together with the colon operator (c)Create a vector version of the original matrix A. (d)Delete the 2nd column of the original matrix A and put it in a variable called A. (e)Insert a 2nd column to the new matrix A to restore it back to its original form A. (f) Extract those entries of the original matrix A that are greater than 5
Enumerate at 8 data structures, and for each item, provide the followinginformation. its common name (e.g. array)a. short description (e.g. stores multiple data elements)b. strength (e.g. retrieval of any element is fast)c. weakness (e.g. adjusting the size (expanding or shrinking the array) isexpensive)
To start, create your own set of 10 numbers in an array that are not sorted. Using your array, do the following exercises: Show how the Mergesort algorithm sorts your array by: 1) Showing which sub parts of the array are being examined with each recursive call to Mergesort 2) Showing the results of the array each time the Merge function is used Your demonstration should be similar to slides 19-33 in the Mergesort presentation. You do not have to show the details of the function calls in the stack (unless it helps you), but do explain what is happening at each step to show understanding of the algorithm. Using your same original array, show how the Quicksort algorithm sorts this array by: 3) Showing the results of the array each time the Partition function is used 4) Showing which sub parts of the array are being examined with each recursive call to Quicksort Your demonstration should be similar to slides 35-64 in the Quicksort presentation. Again, you do not have to show all the…
