Question

MATLAB QUESTION:

I have to write a function that pretty much cleans number.

these are the instructions

Inputs:

number1 - a 1d of array of number, size doesn't matter

outputs:

number2 - all number in number1 that are 0 need to be set to nan and return via number2.

data - storing the number of 0's in number1 that pretty much are being set to nans

here's the code:

function [number2, data] = cleanNumber(number1)

%add your code below..

end

code to call your function

rebuild = [ 205,201,198,0,197,210,220,199,0186,188];

disp("before cleaning numbers:")

disp(rebuild)

rebuild = cleanNumber(rebuild);

disp("after cleaning numbers:")

disp(rebuild)

Answer 1

Here is the function.

function [number2, data] = cleanNumber(number1)

    number2=number1;          % store the number1 in number2
    number2(number2==0)=nan;  % change the numbers with 0s to NaN
    data = sum(number1==0);   % finding the number of 0s

end

Running code for given conditions.

rebuild = [ 205,201,198,0,197,210,220,199,0186,188];

disp("before cleaning numbers:")

disp(rebuild)

rebuild = cleanNumber(rebuild);

disp("after cleaning numbers:")

disp(rebuild)

Output

before cleaning numbers:
   205   201   198     0   197   210   220   199   186   188

after cleaning numbers:
   205   201   198   NaN   197   210   220   199   186   188
