A=
[4951;
5782;
9553;10384]
B=[2;2.5;2.8;3]
C=A.*B or bsxfun(@times,A,B)
the result is
1.0e+04 *
0.9902
1.4455
2.6748
3.1152
why is this so?

Oh. That is not the product of those numbers? Seems right to me, as long as you don't miss that factor of 1e4 out front.
What did you expect?

I don't see the problem. What are you expecting the answer to be?
  • 4951 * 2 = 9902
  • 5782 * 2.5 = 14455
  • etc...

MATLAB has given you the exact values. Do you not understand scientific notation? I suggest you Google it if not. What exactly do you mean by "correct decimal place".
