Problem 5 / MatlabGrader Develop a Matlab function myCubicFit that calculates the coefficients $a_0$ through $a_3$ of the cubic polynomial $f(x) =$ $a_0 + a_1x + a_2x^2 + a_3x^3$ that best fits given data points $(x_i, y_i)$. The input arguments to the function must be the two vectors x and y that contain the values of the data points. The output of the function shall be a four-element column vector a that contains the values of $a_0$ through $a_3$, and the error of the fit E defined as the sum of the squares of the residuals. Do NOT use any Matlab build-in functions to solve the required system of linear equations. Instead use myGaussJordan from Module 2. Use Matlab's ' operator to calculate the transpose of a matrix and * to calculate the product of matrices. Inside the function check that the length of the vectors x and y is the same. If not, display an error message, set the vector a and E to realmax() and exit the function. Problem 5 required submission: Well commented function source code submitted to Matlab Grader

Coding task problem solving: Consider the following programming task. Given an input integer n, create a while loop that utilizes arithmetic to store the frequency of each digit present in n in a dictionary frequency map. The input number n will be provided as a numeric data type, not a string. For each loop iteration, you must update the frequency map before reducing n. Drag the pseudocode steps below to arrange them into the correct order to create a valid solution for the above task.

Let $L = \{8, 16, 24, 32, \dots \}$ be the set of multiples of 8, and let $M = \{45, 90, 135, \dots \}$ be the set of multiples of 45. (a) Find the next four elements of set $M$. (b) Describe $L \cap M$. (c) What is the smallest element of $L \cap M$? (Use a comma to separate answers as needed.) (b) Choose the correct answer below. A. The union of $L$ and $M$, $L \cup M$, is the set of multiples of 8 and multiples of 45. B. The intersection of $L$ and $M$, $L \cap M$, is the set of multiples of 8 and multiples of 45. C. The union of $L$ and $M$, $L \cup M$, is the set of simultaneous multiples of 8 and 45, or the set of multiples of 360. D. The intersection of $L$ and $M$, $L \cap M$, is the set of simultaneous multiples of 8 and 45, or the set of multiples of 360. (c) What is the smallest element of $L \cap M$? (Type a whole number.)
