Using Python Programming Language: 4. Implement the following function in the PyDev module functions.py and test it from a PyDev module named t04.py: def print_matrix_char(matrix): Prints the contents of a 2D list of strings in a formatted table. Prints row and column headings. Use: print_matrix_char (matrix) Parameters: matrix - a 2D list of strings (2D list) Returns: None. Sample testing: Number of rows: 3 Number of columns: 4 0 1 2 3 i 0 с u r 1 с у...
Implement the following function in the PyDev module functions.py and test it from a PyDev module named t15.py: def matrix_equal (matrixi, matrix2): i.e. have the Compares two matrices to see if they are equal same contents in the same locations. Use: equal matrix_equal (matrix1, matrix2) Parameters: matrix1 the first matrix (2D list of ?) matrix2 the second matrix (2D list of ?)

11. Implement the following function in the PyDev module functions.py and test it from a PyDev module named t11.py: def find_word_vertical(matrix, word): Look for word in each column of the given matrix of characters. Returns a list of indexes of all column that are equal to word. Returns an empty list if no column is equal to word. Use: cols - find_word_vertical(matrix, word) Parameters: matrix - the matrix of characters (2D list of str) word - the word to search...
Using Python Programming Language: 3. Write a function flatten that takes a 2D list and returns all the items of each list concatenated together into one new 1D list. For example: flatten ([["a", "b"],["c","0"],["e","f"]]) would return ["a", "b","C","d", "e","f"] Save the function in a PyDev library module named functions.py Write a program t03.py that tests flatten function and prints the returned flat list to the screen. Test your program with a different list, hardcoded in t03.py • Copy the results...
Create a class called Lab7b and in it implement all of the methods below. Also, write a main method with test calls to all of these methods. Don’t forget to turn in your file to Canvas before the end of the lab today. int[][] random(int N, int start, int end) returns an N-by-N matrix of random integers ranging from start to end; int rowSum(int[][] a, int i) returns the sum of the elements in row i of the 2-D array...

Problem 1 Write your code in the file MatrixOps.java. . Consider the following definitions from matrix algebra: A vector is a one-dimensional set of numbers, such as [42 9 20]. The dot product of two equal-length vectors A and B is computed by multiplying the first entry of A by the first entry of B, the second entry of A by the second entry of B, etc., and then summing these products. For example, the dot product of [42 9...
11.3 (Subclasses of Account) In Programming Exercise 9.7, the Account class was defined to model a bank account. An account has the properties account number, balance, annual interest rate, and date created, and methods to deposit and with- draw funds. Create two subclasses for checking and saving accounts. A checking account has an overdraft limit, but a savings account cannot be overdrawn. Draw the UML diagram for the classes and implement them. Write a test program that creates objects of...
Implement a class CSVReader that reads a CSV file, and provide methods: int numbOfRows() int numberOfFields(int row) String field(int row, int column) Please use the CSVReader and CSVReaderTester class to complete the code. I have my own CSV files and cannot copy them to here. So if possible, just use a random CSV file. CSVReader.java import java.util.ArrayList; import java.util.Scanner; import java.io.*; /** Class to read and process the contents of a standard CSV file */ public class CSVReader {...
Question A matrix of dimensions m × n (an m-by-n matrix) is an ordered collection of m × n elements. which are called eernents (or components). The elements of an (m × n)-dimensional matrix A are denoted as a,, where 1im and1 S, symbolically, written as, A-a(1,1) S (i.j) S(m, ). Written in the familiar notation: 01,1 am Gm,n A3×3matrix The horizontal and vertical lines of entries in a matrix are called rows and columns, respectively A matrix with the...
