I need to write a function that requests the user to input 2 numbers one by one and then prints them and their prodct according to:
(I'm using the example numbers it gives me)
>> print_product Give me a number: 4 Give me another number: 7 The product of 4 and 7 is 28.
function [] = print_product ()
clc
x = input('Give me a number: ', 's');
y = input('Give me another number: ', 's');
z = x*y;
fprintf ('The product of x and y is z ')

function print_product()
x = str2double(input('Give me a number: ', 's'));
y = str2double(input('Give me another number: ', 's'));
z = x*y
fprintf('The product of %d and %d is %d',x,y,z)
end

What does that str2double function do? The explanations online don't really help

input('...','s') returns a character vector (a string), and str2double converts that into a numeric (which you need for doing any numeric operations, e.g. times).
