Question

What does the code below do?

clear
vec = randi(20,1,100)-10;
iter=0;
k=1;
while k<= length(vec)
if vec(k)<0
vec(k)= vec(k) * -1;
end
k = k+1;
end

This code generates a vector with 20 random integer elements between 1 and 100, and changes the sign of all negative elements.

This code generates a vector with 20 random integer elements between -100 and 100, and replaces all the negative integers with a positive integer of the same absolute value.

This code generates a vector with 100 random integer elements between -10 and 10, and changes the sign of all negative elements.

This code generates a vector with 100 random integer elements between 20 and 100, and changes the sign of the elements coverting all poivitive ones to negative and all negative ones to positive.

This code generates a vector with 20 random integer elements between 1 and 100, and changes the sign of all the elements.

Expert Solution

Step 1

The code

clear
vec = randi(20,1,100)-10;
iter=0;
k=1;
while k<= length(vec)
if vec(k)<0
vec(k)= vec(k) * -1;
end
k = k+1;
end

This code do :

This code generates a vector with 20 random integer elements between 1 and 100, and changes the sign of all negative elements.
