Question

2.6) Mathlab Exercise
1. Create a row vector v with values (1, 2, 3, 5, 11, 7, 13).
2. Change the value of the 5th and the 6th element of the v to 7 and 11 respectively. Try doing this with only one command as well.
3. Create a vector Five5 out of all multiples of 5 that fall between 34 and 637. By the way, how many are they? (Tip: look up the command ”length” in help.)
4. Double click on the variable Five5 in the Workspace to inspect your results in the Variable Editor.
5. Can you use the colon operator to extract the numbers in the vector Five5 that are multiples of 5 only but not 10 ?

Answer 1

v = [1 2 3 5 11 7 13]
v([5 6]) = v([6 5])
Five5 = int16([]);
a= 1;
for n = 34:637
if(rem(n,5)==0)
Five5(a) = n;
a=a+1;
end
end
length(Five5)
