Question

how can i do this i'm asked to code this but i got no idea how to do it:

"Use vectorisation to achieve the following (no loops or if statements allowed):

create an array x which starts at 0 and ends and 8*pi in increments of pi/100.

create another array y which is equal to sin(x).

then use vectorisation to change all values below the axis to be set to 0"

Hi,

You may find below code useful to solve above question.

x = 0:pi/100:8*pi; 
y = sin(x); 
y(y<0) = 0;
