MATLAB: Need solution asap for the hw about summing each character in student number that we input the data

MATLABsum

num=input('enter your student number here : ');

number is 20758562

how can i sum each number ?

Best Answer

num = input('enter your student number here : ');
NumChar = num2str (num);
MySum = 0;
for i1 = 1:numel (NumChar)
    MySum = MySum + str2double (NumChar(i1));
end
fprintf ('Sum of the numbers is %d', MySum);

MATLAB: How to count the total number of recursion

The problem is that you're not passing num to collatz, so how can it know how many times it has been called? Here is a version that makes num an optional argument, so you don't need to provide it in your call:

function [out, num] = collatz(val,varargin)
if nargin >1
    num = varargin{1};
else
    num = 0;
end
if val == 1
    out = 1;
elseif mod(val, 2) == 0
    [out,num] = collatz(val/2,num);
else
    [out,num] = collatz(3*val+1,num);
end
num = num+1;

Now if you try

[out,num] = collatz(4)

you get

out =
     1
num =
     3

MATLAB: How do you finish this for loop? It is telling me to define the variable “total”, but what do I put in order for it to flow with the loop

total=0;   % you forgot to intialise total ( to define total before usage)
for i = 1:5
 number = input('Enter a number: ');
 total = total + number;
fprintf('The sum of the numbers is %.2f\n', total);
end
