Q5: Write an M-file program to return the summation to each column of any matrix (M) without using sum ( ) function? Q6: Write an M-file program to return the minimum element to each column of any matrix (M) without using min (() function?

1.(a)Write a function named LeastCommonMultiple that takes two integers and returns their smallest common multiple. For instance, least common multiple of 10 and 12 is 60. Create two vectors each having 10 random integers from 2 to 100. Apply the function LeastCommonMultiple to all numbers in your vectors to check their element-wise least common multiples using map2_dbl function in purrr package. For instance, if the random numbers are [2 10 25 13 6 12 11 20 4 8] and [7 6 10 3 12 5 4 30 17 16] then the result should be [14 30 50 39 12 60 44 60 68 16]. (b) Read currency.xlsx file and store its content in a data frame or tibble. The excel file contains daily exchange rates of Bank of Canada. (c)  In order to have one observation in each row, apply pivot_longer function to the data frame and create Currency column which will have a value FXBRLCAD, FXEURCAD, FXTRYCAD, or FXUSDCAD. (d)  Create the following line plot. (e)  Separate the date column into year, month, and day columns (f)…

(a) Write a function matrix_multiply(mat1, mat2) that takes two matrices and returns the result of the matrix multiplication between mat1 and mat2. If the two matrices are not compatible with multiplication, then None should be returned.   (b) Write a function print_sums(list1, list2) that takes two equal-length lists of numbers and prints all the sums of the corresponding elements. Thus the first line is the sum of the first element of list1 and the first element of list2, the second line is the sum of the second elements, and so on.

Part B: For a 2D array of type float, called FiFa, write a statement that declares the array and initializes the first subarray to 5,2,8 the second to 9,7,4 and the third to 3,6,1. How do we pass one row of a 2d array to a function? 1. 2. 3. Explain the relationship between pointers and arrays. What do we mean by file scope? 4. N m

write a program to find the maximum and minimum value from an array content from four element using function by call reference? *

Python question please provide screen shot of the code: SEARCH IN MATRIX You are give a matrix (a list of lists) of DISTINCT integers and a target number. Each row in the matrix is SORTED and each column in the matrix is SORTED. Our matrix does not necessarily have the same height and width. Write a function that returns a list of the row and column indices of the target integer IF it is contained in the matrix, otherwise return [-1, -1]. EXAMPLE INPUT matrix [ [1,4,7,12,15,1000], [2,5,19,31,32,1001], [3,8,24,33,35,1002], [40,41,42,44,45,1003], = [99, 100, 103,106,128,1004] ] target=44 EXAMPLE OUTPUT result = [3,3] Finish the code bellow with given requirements: def search_in_matrix(matrix, target): pass

iii. load_data() takes three strings (filenames) as parameters. These files must have formats similar to movies.csv, ratings.csv, and tags.csv, in this order. Your function must read records from each of these files (except the data in their header rows) and store them in three separate 2-D lists. Let's call these lists movie_db, ratings_db, and tags_db, respectively. Your function must return these lists. If a file cannot be opened, it must print an error message and returns an empty list for that file. Make sure to convert all numeric data to their correct types (e.g., ints or floats) before you store them in a list. The sample output below shows how data should be stored in the returned lists. Since these are 2-D lists, we can use the display_list() function to print their elements as follows. >>> movies_db, ratings_db, tags_db = load_data("movies_20.csv", "ratings_20.csv", "tags_20.csv") >>> display_list(movies_db [2:5]) [3, 'Grumpier Old Men (1995)', 'Comedy | Romance'] [4,…
