I have 1X6 double vector A (where values change during the run):

 0.0155    0.1566    0.0454    0.0146    0.3967    0.1879

I have another 1x6 int32 vector B (where values also change during the run):

120          14          42        2874           7  2147483647

I need to multiply these two and return C=A.*B:

1.86       2.1924         1.9068   ...              403512177.2713

any ideas on how to do it? I have been looking for solution for the past 2 hours and couldnt find anything helpful.

Thank you in advance!

Can't you just use `C = A.*double(B)`? – Luis Mendo May 23 '14 at 11:46
yes it works, i just tried the same – The Minion May 23 '14 at 11:47
@LuisMendo No it doesnt work for me. I get C = 1.0e+08 * -0.0000 -0.0000 -0.0000 -0.0000 -0.0000 -3.5791 – mil May 23 '14 at 11:54
@mil It does work. That's the _correct_ answer. Type `format long` and you'll see – Luis Mendo May 23 '14 at 11:55
Or use `sprintf` to format the result: for example, `sprintf('%15.5f', A.*double(B))` – Luis Mendo May 23 '14 at 12:03
@LuisMendo. Thanks you so much! I had the correct answer but couldnt understand it. Format long and sprintf helped a lot! – mil May 23 '14 at 12:15
