I suspect you want bsxfun() . Try

bsxfun(@times, a.', b)

"so that the answer is for example 10, 100 1000 10000"

b IS 10, 100 1000 10000 - you surely mix up something...

But in general, I suspect, that you look for a .* instead of a * operation.

.* cannot be used when the number of elements is different.

Yes, but this is what users strugle with most (* vs. .*). And as the question is worded so confusing anyway, I was juts throwing out this idea ;-)
