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.

Solutions

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

end

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

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])
