It is. It just doesn't do what you expect it to do.

Why do you say that? "rank = temp(I)" is a valid MATLAB command in this scenario, but so is "rank = I.^2" or "rank = sin(cos(tan(I)))". Each of those commands do something different; for the application you described in your original post, the command that does what you want is "rank(I) = temp".
Although you probably shouldn't use rank as a variable name, unless you're okay with not being able to use the RANK function in the same piece of code.

Yes. And if you wanted to store 1:4 into the 7th, 4th, 9th, and 1st elements of A, you'd use:
A([7 4 9 1]) = (1:4);
Just because one command works does not necessarily rule out a modification of that command also working and doing something slightly different.
