Hi, I would like create a vector using a for loop.

P=1e3;
i=6;
for i=1:length(i)
X(i)=P/1e3
end

I expect following results

X=[1e3 1e0 1e-3 1e-6 1e-9 1e-12 1e-15]

Thank you in advance!

Answer 1

[Birdman]

P=1e3;
n=7;
for i=1:n
    X(i)=P/10^3;
    P=P/10^3;
end

Answer 2

[Andrei Bobrov]

n = 7;
P = 1e3;
X = P * 1e-3.^(0:n);

The users wants a loop.

+1 the simpler MATLAB way of doing this.

@Birdman: lots of users come here asking for "how to do XXX in a loop", and are surprised to learn that MATLAB has simpler, more efficient ways of doing things: they did not realize that loops were not required! It is entirely appropriate on this forum to point this out, and to show how.
