Next, add to you derivative function the capability to check for accuracy by comparing maximum errors between successive calculations of the derivative. You will need a while loop that checks when the maximum error is ≤ eps. To find the maximum array create a numpy array in your derivative function. Call it "maxe" where each element of the array would contain |dƒj+¹(x;) – dƒ³ (xi)|. j + 1 refers to the finer grid where the j + 1 grid would use twice as many points as the j grid. For example, j = 1 (the starting grid) would have N = 10 points, and the j + 1 grid would use 2N = 20 points, the j + 2 grid would use 40 points and so on. Now for the 1st pass through the while-loop you cannot converge you haven't started the comparison. So construct you code to avoid this situation. For this part of the laboratory, let's use for our function, f(x) = x logx

In a one-dimensional array, one-year average daily temperature information of the city of Karabük is kept. The average daily temperature information is between -25 and 35 degrees. Accordingly, write a function that takes this array as a parameter and finds the number of temperatures between [-25, -10), [-10, 5), [5, 20) and [20, 35] values and prints it to the screen in that order. Sample Output ( Example Output ): [-25, -10) : 13 [-10, 5) : 93 [5, 20) : 117 [20, 35] : 142
Given a square matrix, calculate the absolute difference between the sums of its diagonals. For example, the square matrix is shown below: 1 2 3 4 5 6 9 8 9 The left-to-right diagonal = . The right to left diagonal = . Their absolute difference is . Function description Complete the function in the editor below. diagonalDifference takes the following parameter: int arr[n][m]: an array of integers Return int: the absolute diagonal difference Input Format The first line contains a single integer, , the number of rows and columns in the square matrix .Each of the next lines describes a row, , and consists of space-separated integers . Constraints Output Format Return the absolute difference between the sums of the matrix's two diagonals as a single integer. Sample Input 3 11 2 4 4 5 6 10 8 -12 Sample Output 15 Explanation The primary diagonal is: 11 5 -12 Sum across the primary diagonal: 11 + 5 - 12 = 4 The secondary diagonal is: 4 5…
Write a maxConsecutiveDiff function which returns the maximum difference between any two consecutive values in the array.Consecutive values are next to each other in an array (+/- 1 index)This function should accept all required data as parameters.ExamplesIf the array is 17 15 16 11 14 the maximum consecutive difference is 5 which is the difference between 16 and 11.If the array is 10 13 11 12 19 the maximum consecutive difference is 7 which is the difference between 12 and 19.
In this assignment, you will decide how to keep the inventory in the text file. Then your program must read the inventory from the file into the array. Each product must have a record in the file with the name, regular price, and type. There are several options for storing records in the file. For example, • each value takes one line in the file (i.e., three lines for one product). Then you must take care of correct handling of the ends of the lines; • all values are in one line that can be read as a string. Then you must handle the parsing of the string; • all values are in one line separated by a delimiter. Then you must handle a line with delimiters. Assume that the inventory does not have more than 100 products. But the actual number is known only after the reading of the file. Once you can read data from the file into the array, you must add a new property to the product class – a static variable that holds the number of products in the inventory. Its value must grow as reading…

you need to insert only the even index values to an array named intArray[]. Now send that array to a function named int sumOfallArrayElements(int *intArrayLocal) where you need to sum all the elements of all the array elements and return back to the main function. PLEASE DO NOT USE ANY INDEX TO ACCESS ELEMENTS OF THE ARRAY. Sample Output:Elements of intArray: 0 2 4 6 8 10 12 14 16 18Sum of all evenindex elements is: 40
I'm trying to create two functions where each calculates a cube. One that uses numpy and uses function power and can't use for loops. Other uses a range of intergers and returns a list of each range elements using pow. I can get each to cube but I can't figure out how to do it by defining a function. import numpy as nparray1 = np.array([3,5,10,9]) cubedarray1 = np.power(array1, 3)print('This is the cubed arrray 1: ', cubedarray1)array2 = range(1,10,2) # range is 1, 3, 5, 7, 9cubedarray2 = [pow(i, 3) for i in array2]print('This is the cubed array 2: ', cubedarray2)
In statistics the median of a set of values is the value that lies in the middle when the values are arranged in sorted order. If the set has an even number of values, then the median is taken to be the average of the two middle values. Write a function that determines the median of a sorted array. The function should take an array of numbers and an integer indicating the size of the array and return the median of the values in the array. You may assume the array is already sorted. Use pointer notation whenever possible.

It is a written project, you just need to submit a text file in txt, or docx or pfd format and don't have to submit your testing codes. For the following array x [10] = { 45, 20, 50, 30, 80, 10, 60, 70, 40, 90}show the contents of x after the function call split Pos = split(x, 0, 9) is executed, and give the value of the array index splitPos (the first is the pivot). Modify quicksort() to incorporate this modification: In quicksort, we do not splitting sublists further when they have fewer than LOWER_BOUND elements for some constant LOWER_BOUND. When execution of the quicksort algorithm terminates, simply sort the whole list using insertion sort. Include the modified code in this document Use the similar diagram as for merge-sorting the following list of numbers : 8, 2, 9, 4, 5, 3, 1, 6 Upload your solutions in a document file.
create a flowchart from the user-defined array for any size n determined/chosen by the user to the function that determines the perfect squares in an array. Display theresult as an ordered pair (u, v) where u is a perfect square and v is its corresponding squareroot. Call this function to find all perfect squares of the array.
