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...

MATLAB code help!! Homework 3 - Arrays, Masking, Systems of Equations, Plotting, and Numerical Methods Function Name: sysEq Inputs: 1. (double) An NxN array representing an A matrix 2. (double) An Nx1 vector representing a b matrix Outputs: 1. (double) An Nx1 vector representing the resulting x matrix Background: Whoo, who woulda thunk it? Actually useful things in MATLAB? You bet! This method of solving systems of linear equations is useful in a wide variety of places, from solving mesh...
in python 3 1. A program contains the following function definition: def cube(num): return num * num * num Write a statement that passes the value 4 to this function and assign its return value to the variable result. 2. Write a function named get_first_name that asks the user to enter his or her first name and returns it.
ANSWER USING PYTHON Write a recursive function that takes 2 sorted lists as arguments and returns a single, merged sorted list as a result. For example, if the two input lists are [0, 2, 4, 6, 8] and [1, 3, 5, 7, 9], the returned result should be [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]. Remember that you can add lists in Python using the + operator ([0] + [1,2,3] = [0,1,2,3]) and can take slices of...
(20 points) ) Write a Python program which merges two sorted singly linked lists and return it as a new list. The new list should be made by splicing together the nodes of the first two lists. Example: Example: Input: 1->2- >4, 1->3->4 Output: 1->1->2->3 ->4->4
Need help writing these functions in Python: FUNCTION 1 get_course_ids: Consumes a list of Course dictionaries and returns a list of integers representing course IDs. Here's what I have so far but I'm getting a Type Error - list indices must be integers or slices, not dict. def get_course_ids(courses): course_ids = [] for course in courses: course_ids.extend(courses[course]) return course_ids FUNCTION 2 choose_course: Consumes a list of integers representing course IDs and prompts the user to enter a valid ID,...
