Why does the loop not work for the increment stated?

for t= 0:1:20
a= [t, sin(t), 0];
b= [0, 0, cos(t)];
v= a + b;
end

The loop only calculates the value of v for 20, not 0 to 20 as stated by the increment. What have I done wrong? I need it to calculate the vector v for numbers 0 all the way to 20.

Your code is essentially correct. If you want all the itermediate results, you need to index ‘v’:

for t= 0:1:20
a= [t, sin(t), 0];
b= [0, 0, cos(t)];
v(t+1,:)= a + b;
end

Sorry but how would I do that? I changed the code to what you have shown but it doesn't work.

" I changed the code to what you have shown but it doesn't work."

What exactly does "it doesn't work" mean? I tried Star Strider's code and got this:

v =
    0.00000    0.00000    1.00000
    1.00000    0.84147    0.54030
    2.00000    0.90930   -0.41615
    3.00000    0.14112   -0.98999
    4.00000   -0.75680   -0.65364
    5.00000   -0.95892    0.28366
    6.00000   -0.27942    0.96017
    7.00000    0.65699    0.75390
    8.00000    0.98936   -0.14550
    9.00000    0.41212   -0.91113
   10.00000   -0.54402   -0.83907
   11.00000   -0.99999    0.00443
   12.00000   -0.53657    0.84385
   13.00000    0.42017    0.90745
   14.00000    0.99061    0.13674
   15.00000    0.65029   -0.75969
   16.00000   -0.28790   -0.95766
   17.00000   -0.96140   -0.27516
   18.00000   -0.75099    0.66032
   19.00000    0.14988    0.98870
   20.00000    0.91295    0.40808
   

What do you expect to get?

I tried again and that's what I got. Thanks for the help.
