I want to multiply 2 arrays

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?

Answer 1

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?

doc format

how to get the exact numbers?without this 1e4 format

[Guillaume]

As per John's anwser:

doc format

Or if it's really that hard to type that into matlab, click on this link

Personally, I use format longg

Answer 2

[David Barry]

I don't see the problem. What are you expecting the answer to be?

• 4951 * 2 = 9902
• 5782 * 2.5 = 14455
• etc...

the exact values..correct decimal place

[David Barry]

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".
