Create a Doubling Series
显示 更早的评论
I am trying to use Matlab to create a series in which each term is the double of the previous term (ie. 1*2=2, 2*2=4, 4*2=8 etc.), but I can't find an effective way to do this. Any tips?

How would you do this starting with any given number? i.e. starting with 250 and getting 500, 1000, 2000, 4000, 8000, etc...

Choose ‘limit’ to be whatever you want:
limit = 10;
Out = 2.^[1:limit];
fprintf(1, [repmat('%6d',1,limit) '\n' repmat('%6d',1,limit) '\n'], [[1:limit]; Out]')
1 2 3 4 5 6 7 8 9 10
2 4 8 16 32 64 128 256 512 1024

Try this:
Out = 250 * 2 .^ (0:6)
producing:
Out =
250 500 1000 2000 4000 8000 16000
