This is python: #Write a function called count_positive_evens. This function #should take as input a list of integers, and return as #output a single integer. The number the function returns #should be the count of numbers from the list that were both #positive and even. # #For example: # # count_positive_evens([5, 7, 9, 8, -1, -2, -3]) -> 1 # count_positive_evens([2, 4, 6, 8, 10, 12, 15]) -> 6 # count_positive_evens([-2, -4, -6, -8, -10, 1]) -> 0 # #0...

Using Matlab, write a function that takes numeric data as its input argument and prints a message to the Command Window stating if the number is positive, or negative, or 0. This function should transfer an output value to the Workspace ONLY when the input value is negative. Please include a copiable code and the associated screenshots.

Write a recursive function (using Matlab) moreFactors(a,b,fact) that does the following: 1. Takes as an input 3 positive integers. 2. Of the two integers a and b, the function returns the integer that has the most factors fact. 3. If both integers a and b have the same amount of factors fact, the function will return the larger integer. Test your function with the following: >> result=moreFactors(24,32,3) result = 24 (24 = 3^1 · 2^3 , 32 = 2^5 )...

A. Write a function in MATLAB called findTranspose that takes in as input any matrix or any vector and simply returns back the transpose of that input. You can always verify your answer by using the inbuilt transpose function in MATLAB, however, you cannot use the transpose function directly when writing your code. Here is the starter code that we are providing to help you get started %x is the input vector or matrix. You can find the %size that...

Write a function in Matlab that takes as input the number n and a symmetric tridiagonal matrix given as two vectors: n×1 vector v representing the main diagonal and (n−1)×1 vector w representing the upper diagonal. Have this function output the Cholesky factor of the matrix as a vector for the main diagonal and a vector for the upper diagonal and output the number of flops and, separately, the number of square roots used as well. Use only basic programming....

Write a MATLAB function that accepts input vector x and returns the number of local maximums of x with value between xmin and xmax. Ask user to input values xmin and xmax at the beginning of the procedure. Use vector x (the vector x from that file consists of 1000 numbers ranging from 0.0044 to 0.67).

B. Write a function in MATLAB called findInverseOf2x2Matrix that takes in as input any square matrix of size 2 × 2 and returns back the inverse of that matrix if one exists. If no inverse exists, print back a suitable error message. You can safely assume that we will test your code on square matrices of size 2 × 2 only. You can always verify your answer by using the inbuilt inverse function in MATLAB, however, you cannot use the...

Using Python Question 1 Write an input function. Then use it to supply the input to following additional functions: i) Print multiplication table of the number from 1 to 12. ii) Print the sum of all the numbers from 1 to up the number given. iii) Print if the number supplied is odd or even. Question 2 Write function that asks for input from a user. If the user types 'end', the program exits, otherwise it just keeps going.
