4. What change/changes can be made in the following code to make it more efficient? n = randi ([2 100]); for iv = 1:n inputnum = input ('Enter a number: '); numvec (iv) = inputnum; end fprintf('The vector is: \n'). disp (numvec)

Answer 1

#source code:

n=randi([2 100])
numvec=zeros(1,n)
tic
for iv=1:n
numvec(iv)=input('Enter a number: ')
end
toc
fprintf('The vector is:\n')
disp(numvec)

OUT AWNE n=randi([2 100]) numvec=zeros(1,n) tic for iv=1:n numvec(iv)=input("Enter a number: '); end toc fprintf('The vector is:\n') disp(numvec)

prezeros allocation can increase the speed of execution.

for loop must iterate n times so we can't modify the loop and within for loop two statements are present so

if n=20 with the statements need 2*20 so 40 times

so but make it one line we can used 20 times only

tic and toc are used ti display the time taken the program..
