for loops out of bounds

I want to make an array with a list of values from 0 to pi in steps of 0.5, my code was

for loop i=0:0.5:pi;
    i
end

when I do this i get a list of values but then when I type i, i only get the last value of the for loop, is there any way to get i to equal all the values separaelty? When i try and do i(2)/i(3) an error message comes up which says it is out of bounds ( assuming it thinks i only has 1 value), thanks in advance

for loop i=0:0.5:pi;

This is no valid Matlab syntax. You can run code directly in the forum's interface and you will get an error message for this. A valid loop would be:

 for i=0:0.5:pi     

This creates i=0, i=0.5, ... iteratively. Of course all i are scalars - this is the purpose of a loop counter.

Your pseudo-code contains the solution of your problem already: Simply omit the for loop, but define the output directly:

i=0:0.5:pi;

Now you can access w.g. i(2) and i(3).

I suggest the free Matlab tutorial to learn such basics: https://www.mathworks.com/learn/tutorials/matlab-onramp.html

i = 0:0.5:pi

i = 1×7

0 0.5000 1.0000 1.5000 2.0000 2.5000 3.0000
