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()
You are designing a function that will manipulate an array of integers. It needs to work for arrays of any length. What is the minimum number of parameters your function will have?
Do this using C++. Initialize an integer array with random number between 0 to 51 using rand() function. And search one random generated key element from this array. If match not found, an error must be print on screen "key not found" or "element not found in the list". Searching technique "linear search"
Programming in C language. RandomNumbers Declare an integer array locally with the size of 200. Create a program that asks the user how many numbers the have. Use your getChoicel) function from before. Make sure it does not exceed 200 as the locally declared array has the size of 200. Use a loop to assign random numbers from 1 to 10000 to the array elements. (Remember to use srand() to seed the random number generator). Use a second loop to display each number, and also determine the average of all values in the array. You must also find the largest and the smallest numbers. After the for loop, display the average of all numbers. This program will let you enter a list of numbers into an array. It will then display all of the numbers, and finally display the average of all numbers. How many numbers would you like to enter?10 Number 1 is 42 Number 2 is 8468 Number 3 is 6335 Number 4 is 6501 umber 5 is 9170 Number 6 is 5725 Number 7 is 1479 Number 8 is 9359 Number 9 is 6963 Number 10 is…
By using C++ program Write an application that solves a system of linear equations. Have the user input the coefficients of the two lines. Remember that the definition of a line is: Ax + By = C. You can use any method you wish to solve. The program should output the intersection of the two lines if they do indeed intersect, indicate if the two lines are parallel, or if they are the same line. Note: use an Array.

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…

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…
dont give the same solution again .10 min left fast Array creation: There are various ways to create arrays in NumPy. O For example, you can create an array from a regular Python list or tuple using the array function. The type of the resulting array is deduced from the type of the elements in the sequences. O Often, the elements of an array are originally unknown, but its size is known. Hence, NumPy offers several functions to create arrays with initial placeholder content. These minimize the necessity of growing arrays, an expensive operation. For example: np.zeros, np.ones, np.full, np.empty, etc. O To create sequences of numbers, NumPy provides a function analogous to. range that returns arrays instead of lists. O arange: returns evenly spaced values within a given interval. step size is specified. O linspace: returns evenly spaced values within a given interval. num no. of elements are returned. O Reshaping array: We can use reshape method to reshape an array. Consider an array…
In C++ Create an array in main of size 100. Fill it with random odd numbers. Find the max number in the array.
Code for this in C: You have created three arrays:array A of size 100array B of size 50array C of size 200You are to store the first 100 numbers (1,2,3,...,100) into array A, the first 50 positive odd numbers (1,3,5,...,) into array B, and the reciprocal of each position [C(5) = 1/5] into array C. Then, output the contents of each array.
