In MATLAB define a function named primes that takes a non-negative integer, ?, as its only argument and returns a row vector containing the first ? prime numbers in order. Assume that the first prime number is 2. Other than the zeros function, the ones function, and the colon (:) operator, you may not use any Matlab built-in array functions.

Expert Solution

function [primes] = findFirstNPrimes(N)

%returns the array with first n primes

%first prime

primes(1) = 2;

i = 3;

while length(primes) <= N

%taking remainder with all the primes so far

remainder = mod(i,primes);

% if all inNotPrime is 0 the number is a prime since remainder is

% not zero for all the numbers in prime

isNotPrime = sum((remainder == 0));

%adding prime number to the array

if (isNotPrime==0)

primes(end + 1) = i;

end

%checking for next the number

i =i+ 1;

end

PYTHON 3: Write a recursive function that takes a non-negative integer n as input and returns the number of 1's in the binary representation of n. Use the fact that this is equal to the number of 1's in the representation of n//2 (integer division) plus 1 if n is odd. >>>numOnes(0) 0 >>>numOnes(1) 1 >>>numOnes(14) 3

C++ Only Create a function named PrintStudents, which takes a string input filename and an integer minimum score value and a string output file name as a parameters. The function will read the student scores and names from the file and output the names of the students with scores greater than or equal to the value given. This function returns the integer number of entries read from the file. If the input file cannot be opened, return -1 and do...

Write a MATLAB function named numberWords() that takes a whole number as an argument and returns a string containing the number word for the whole numbers 0 - 999. For example: numberWords(234) would return 'two hundred thirty-four' If the input value is not a whole number between 0 - 999 then the function should return a string equivalent to 'ERROR'.

Write a function named hasNValues which takes an array and an integer n as arguments. It returns true if all the elements of the array are one of n different values. If you are writing in Java or C#, the function signature is int hasNValues(int[ ] a, int n) If you are writing in C or C++, the function signature is int hasNValues(int a[ ], int n, int len) where len is the length of a Note that an array...

in c++, please provide only a function. the function should be named "tally." it takes no parameters but returns an int. the first int should be 0, next being 1, then 2, etc.. will rate if correct. again should only be 1 function.

Write a function that takes a numeric or integer vector and adds up only the numbers...

Write a function that takes a numeric or integer vector and adds up only the numbers whose integer parts are even. Modify your answer to question above to include an option that allows you to choose whether to sum numbers whose integer parts are even or are odd. Your function should have as a default that it gives the same output as the function in question 4. In other words, if the user doesn’t specify whether to sum evens or...

2. Define a function max_n(arr, n) that takes in an array and an integer as arguments. Your function will then return the n largest values from that array as an array containing n elements. It is safe to assume that arr will have at least n elements. The resulting array should have the largest number on the end and the smallest number at the beginning. For Example: max_n(np.array([1,2,3,4,5]), 3) returns np.array([3,4,5]) max_n(np.array([10,9,8,7,6,5]), 4) returns np.array([7,8,9,10]) max_n(np.array([1,1,1]), 2) returns np.array([1,1])

Function named FunCount takes three arguments- C, an integer representing the count of elements in input list IP- input list of positive integers. Item- an integer value. Function FunCount returns an integer representing the count of all the elements of List that are equal to the given integer value Key. Example: Don’t take these values in program, take all inputs from user C = 9, IP= [1,1,4,2,2,3,4,1,2], Item = 2 function will return 3 IN C PROGRAMMING

Write a method called recursiveDownAndUp() that takes one non-negative integer parameter, recursively starts at one thousand and prints all the integers from one thousand to the parameter (that is, prints 1000, 999, etc. all the way down to the parameter), then recursively starts at the integer parameter and prints all the integers from the parameter up to one thousand (that is, prints the parameter, the parameter + 1, the parameter + 2, etc. all the way up to 1000). Hint:...
