Create the following matrices with the help of the matrix generation functions eye, ones, diag and triu. See the on-line help on these functions if required (i.e. help eye). Do not enter the matrices explicitly. Each matrix should be generated with a single command. [c c a 00 [b b b [200] M= 0 a 0, N= 0 b b P= 0 3 0, Q = с 10 0 a 00 b 004 The variables a, b and c are already created for you. C C

Using the data file below design a hierarchical struct to organize the data. Then declare an array of structs for the reservations. The data file contains ten reservations. There are 8 columns of data: party name, size, date and time for the reservation, phone number, email address, credit card number and expiration date for the credit card. The data can be read from the file below so you will not need to type it in repeatedly. Once you have populated the array with data perform the following tasks: Write a function that will print out to the screen the information for one reservation.In the main program write code that prompts the user to enter a date in the form MM DD YYYYCall the function to print out all reservations on that date. You can make a loop that calls the print function repeatedly or you can put that code inside the print function.TEST CASES: April 30, 2023 and May 12, 2023. In this example you need to carefully consider what data types to use. For example, the credit…
1.Description: You are given a list of queries, each consisting of three integers: a, b, and k. Your task is to perform a series of operations on an array of size n such that each element in the array is incremented by k in a specific range defined by a and b.. Coding expansion.

Use Matlab commands to load mat into the workspace, then use the information in the inventory variable to answer the following questions. You must show all of your Matlab calculations Part A: Calculate and display the maximum value in each column as a single vector. No labeling is needed. Your output should be: ans = 99 66 Part B: Create a new matrix named inventory_subset from the second, fourth, and final row of inventory. Your new matrix should have 3 rows and 2 columns and the output should be: inventory_subset = 99 -3 57 21 40 41
Vector Creation (creating equally spaced vectors) Write a script with commands to create the following vectors and assign to the indicated variable names. ■ Create an evenly-spaced row vector A with elements starting at 0 and ending at 50 with increments of 0.5. ▪ Create a row vector B with 80 evenly-spaced elements starting at 0 and ending at л/2. Your code should not include the following MATLAB functions or keywords: for, while. Hint: one line of your solution should start with A = and the other line of your solution should start with B =
I need to merge three datasets so that I can create a custom function that would do the following: Create a function called theme_by_year that takes as input a year (as an integer) and shows the theme ids and theme names (listed in order by theme id) that were in sets that year. The column names must be id and name_themes (to differentiate between the name of a theme and the name of a set) in that order. The index should be reset and go from 0 to n-1. Each theme should only be listed once even if it appeared in more than one set from that year -- duplicate themes should be based on theme id and not name since there are some themes with the same name but with a different id. Hint: It will help if you were to think about merging appropriate DataFrames to help you get this answer. The desired output should look like this: theme_by_year(1960) Output: id name_themes0 371 Supplemental1 497 Books2 513 Classic Here's what I tried, but I did not get the desired output:
3. Load the file thermocouple.dat. Save the data in a matrix named thermo- couple. (a) Create a column vector named times going from 0 to 24 in 2-hour incre- ments. (b) Combine the times vector you created in part (a) with the data from thermocouple to create a matrix containing the times and the thermo- couple data. (c) Recall that the max and min functions can return not only the maximum and minimum values in a column, but also the element number where those values occur. Use this capability to determine the values of times at which the maxima and minima occur in each column. PARTNERE ME
Create a visitors application that prompts the user for the number of visitors each day for the past 5 days and then displays the average number of visitors per day. (use & to accept new value) Use PL/SQL Array (NUMBER type basic composite array type ) and array has to have 5 members only. The application output should look like same as following: Test: If you receive below numbers from user then your average should be 234. Display avarage on screen. 1: 150 2: 220 3: 180 4: 300 5: 320 The average number of visitors is: 234 Hint : Once you create Array DECLARE TYPE my_array_type IS TABLE OF number INDEX BY PLS_INTEGER; v_n_array my_array_type; Then in the BEGIN and END block accept new value for each array members. DO NOT Use LOOP to accept new & as it is not design to get new value via loop.. Instead use separate 5 different &substitution value to get each values from user input BEGIN…

03/ Create the following matrix M (do not type individual elements explicitly): 9 27 81 12 8 4 3 16 5 100 15 25 35 83 66 49 Do not type individual elements explicitly, use the matrix M to: (a) Delete the fourth row of matrix M and put the new matrix in MN, then create a 3x3 matrix named A that contains the first, second and fourth columns of MN. (b) Add a fifth row to the matrix M with the elements similar to that of the third column, then find the matrix summation and average and display the results using the fprintf command.
