Q // Write a program in C++ language that enters a number of integer numbers into a singular matrix whose size is renewed after asking the user about the number of numbers he wants to enter, then he collects these numbers and prints the result on the screen
Java Program Your program should use 2D arrays to implement simple matrix operations. Your program should do the following: • Read the number of rows and columns of a matrix M1 from the user. Use an input validation loop to make sure the values are greater than 0. • Read the elements of M1 in row major order • Print M1 to the console; make sure you format as a matirx • Repeat the previous steps for a second matrix M2 • Create a matrix M3 that is the transpose of M1 and print it to the console • Check if M1 and M2 can be added (should have the same dimensions). If possible, add M1 and M2 and print the result to the console. Otherwise print an error message. • Extra credit: Multiply M1 and M2 if possible and print to the console. If the matrices cannot be multiplied, print an error message. Implementation requirements: • Use a helper method for reading a positive integer using an input validation loop. • Use a helper method for printing a matrix. Your helper methods should be private and…
(Algebra: multiply two matrices) Write a method to multiply two matrices. The header of the method is: public static double[][] multiplyMatrix(double[][] a, double[][] b) To multiply matrix a by matrix b, the number of columns in a must be the same as the number of rows in b, and the two matrices must have elements of the same or compatible types. Let c be the result of the multiplication. Assume the column size of matrix a is n. Each element cij is ai1 × b1j + ai2 × b2j + g + ain × bnj. For example, for two 3 × 3 matrices a and b, c is where cij = ai1 * b1j + ai2 * b2j + ai3 * b3j . Write a test program that prompts the user to enter two 3 * 3 matrices and displays their product. Here is a sample run: Ps: pls do the same header and the output is the same on the picture thanks

OCAML programming (Lights Out) The mechanics described in this exercise can be used to implement a game lights out. 1. Create a function flip val flip : bool array array -> int -> int -> bool array array = <fun> that given a bool matrix and two integers i; j. it negates the values(true!false, false!true) at location i; j in the matrix, as well negatingthe values on the (up to) 4 horizontally/vertically adjacent elements. 2. Create a function print matrix val print_matrix : bool array array -> unit = <fun> that given a bool matrix, it prints it on screen (true !"T", false!"F"). Sample input: # let matrix= [|[|false; true; true; false|]; [|true; false; false; true|];[|false; false; true; true|]|];;# print_matrix matrix;;FTTFTFFTFFTT# flip matrix 1 4;;# print_matrix matrix;;FTFTTFFFFFTT
java programming language *matrices refers to 2d arrays note: In the question, it is asked to rotate the points(counterclockwise) inside of the matrix, obviously not the matrix itself. For example,|[1, 2]| -> |[1.866, 1.232]||[3, 4]| (30deg) => |[4.598, 1.964]||[5, 6]| -> |[7.330, 2.696]| it should work in any Nx2 matrice like 2x2, 3x2,4x2. N and the angle (in degrees) should be determined by the user
In java Develop a function that accepts an array and returns true if the array contains any duplicate values or false if none of the values are repeated. Develop a function that returns true if the elements are in decreasing order and false otherwise. A “peak” is a value in an array that is preceded and followed by a strictly lower value. For example, in the array {2, 12, 9, 8, 5, 7, 3, 9} the values 12 and 7 are peaks. Develop a function that returns the number of peaks in an array of integers. Note that the first element does not have a preceding element and the last element is not followed by anything, so neither the first nor last elements can be peaks. Develop a function that finds the starting index of the longest subsequence of values that is strictly increasing. For example, given the array {12, 3, 7, 5, 9, 8, 1, 4, 6}, the function would return 6, since the subsequence {1, 4, 6} is the longest that is strictly increasing. Develop a function that takes a string…
Please Help me with This Problem Language = C++ Write a Menu Driven C++ program that creates a two-dimensional array/Matrix of size n X m where nrepresent the students and m represent the subjects and initialize it with user. The program should dofollowing Tasks using Menu, the menu operations are implemented using functions:a) Total_Marks: Calculates total/sum of the values in the specified row (student).b) Avg_Subject: Calculates Average of the values in the specified column (subject).c) Stud_Highest: Finds highest value in the specified row of the array and return that subjectname.d) Stud_Lowest: Finds lowest value in the specified row of the array and return that subject name.
Multi Dimensional Arrays in C Program Ask the user for the number of rows and columns of a two-dimensional array and then its integer elements. Then, ask the user for another integer value which represents a boogeyman. A boogeyman is a value that we intend to find from a given array. Find and output the coordinates of the boogeyman by this format: "BOOGEYMAN LOCATED AT ROW {row_number}, COLUMN {column_number}!" Input 1. One line containing an integer for the number of rows 2. One line containing an integer for the number of columns 3. Multiple lines containing at least one integer each line for the elements of the array Sample 1 4 2 3 9 1 2 3 4 2 1 1 9 2 8 3 4. One line containing an integer for the boogeyman's value Output Print the row of the position first and then the column of the position. Note that the row and the column is 0-based (i.e. it starts at 0 and not at 1). It is guaranteed that the boogeyman exists and only once in the 2D array. Enter# of rows: 4 Enter…
