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

Prompt: In Python language, write a function that applies the logistic sigmoid function to all elements of a NumPy array. Code: import numpy as np import math import matplotlib.pyplot as plt import pandas as pd def sigmoid(inputArray): modifiedArray = np.zeros(len(inputArray)) #YOUR CODE HERE: return(modifiedArray) def test(): inputs = np.arange(-100, 100, 0.5) outputs = sigmoid(inputs) plt.figure(1) plt.plot(inputs) plt.title('Input') plt.xlabel('Index') plt.ylabel('Value') plt.show() plt.figure(2) plt.plot(outputs,'Black') plt.title('Output') plt.xlabel('Index') plt.ylabel('Value') plt.show() test()
Write a loop snippet (just a piece of code, not the whole program) that will sum every third element in a 1D array. The size of the array is held in the variable MAX. You will start with the first element in the array. The name of the array is testarray.
Program: Using a multidimensional array, create a triangular-shaped array. You will ask the user how many lines they want to see and then create the array, fill it, and then print it. You will fill the array with one 1 in the first row, two 2’s in the second row, etc. This should work for any integer that the user enters. (Just because I am starting on 1 does not mean row 0 was skipped.) You must: use a loop to create the array shape. You must: use nested for loops to fill the array and to print the values back to the screen. Your program should print as shown below. Example Output: How many lines would you like in your triangle? >>>9 1 2 2 3 3 3 4 4 4 4 5 5 5 5 5 6 6 6 6 6 6 7 7 7 7 7 7 7 8 8 8 8 8 8 8 8 9 9 9 9 9 9 9 9 9 If your code looks like the code below, it is not what I’m asking for. The code below is making a square multidimensional array, not a triangular one. The code below is just leaving certain spots empty so that it looks like a triangle. I will ask you…

ASSIGNMENT: Working with Vectors Write a menu-driven program that will allow the user to run any of the following questions. Please put the functions headers in h file and the functions definitions in a .cpp file. 1. Write C++ code for a loop that simultaneously computes both the maximum and minimum element in a given vector. 2. Write a function double scalar_product(vector a, vector b) that computes the scalar product of two vectors. The scalar product of two vectors A[al, a2, a3) and B(bl, b2, b3} is another vector C given by C{c1, c2, c3} where cl = al * b1, c2 = a2 + b2, c3 = a3 + b3. 3. Write a function that computes the alternating sum of all elements in a vector. For example, if alternatingSum() is called with a vector containing 149 16 9 7 4 9 11 then it computes 1-4+9-16+9-7+4-9+11=-2 4. Write a procedure reverse that reverses the sequence of elements in a vector. For example, if reverse is called with a vector containing 1 49 16 9 7 4 9 11 then the vector is changed 11 9 4 7…
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)

1. Suppose, you need to create an n xm matrix where n and m will be provided by user. Write a code that can find out the addition of all the elements of first row and last column of it.
In [ ]: We obtained an array with N = 10 values, scattered about mean of 25 (mm). Let's calculate the mean, standard deviation, standard deviation of the mean and 20-uncertainty SL of these numbers. In the following code, do these steps: • In the first cell, add a brief comment that explains what each statement does. Start each comment with a # sign. • In the second cell, delete the raise Not ImplementedError() code line and print the standard deviation and 20-uncertainty on the screen (follow the example for mean_L) mean_L = np.mean (L) print("Mean length: ", mean_L) stddev_L = np. std (L, ddof=1) stddev_mean_L = stddev_L/np.sqrt(N) uncertainty_L = 2*stddev_mean_L In [ ] V #YOUR CODE HERE raise NotImplementedError() #calculates the mean of L In the above code, the green expressions on the right hand side, such as np.mean, np. std and np.sqrt are functions built into the numpy package of Python. The names on the left hand side are variable names invented by me.
I have an error inside my simple javascript code, I want you to fix it. The code is simple. The code is supposed to print an array with 10 elements, but when it comes to one element inside the array, it is supposed to concatenate a string value The problem with my code is it is printing all elements of the array, but it is not concatenating a string to one element. The problem is inside my print_array_changed function Generally, the code is required to print all elements with one element having a concatenated string. Look inside the print_array_changed function and fix it to attain the desired goal Code // create an array and assign values inside it const Employees = [ "JACK", "JILL", "Homer", "Lisa", "Bart", "Marge", "Burns", "Maggie" , "Amy", "Bill", ] // This function prints all elements…
