## Homework Statement

Calculate the time taken to compute sum of 1/k^3 from 1 -> 1000 using both loops and vectorised commands using tic toc.

## Homework Equations

## The Attempt at a Solution

tic

n = 1e3; % number of terms in the sum

s = 1; % accumulator variable (for the sum)

for k = 2:n

s = s + 1/k^3;

end

s; % print value of variable s

toc

k = 1:1000;

y = 1./k.^3;

sum(y);

toc

Am I using tic toc in the correct way? If not, how should they be used and if I run this code will the time be displayed in the command window?
