Fixe the number of digit when creating matrix

I try to create a matrix with 2 objects: A a list of numbers with 4 digits B a matrix of numbers with 0 digits

I used M = [A, B]

But when I do that I lose the 4 digits of A and all numbers in my matrix have 0 digits. How to keep the numbers of digits of A while creating the matrix?

Thanks

Give an example of the numbers you mean. Are you mixing types? What does

whos A B

show?

Name            Size                Bytes  Class     Attributes

A        2420000x1              19360000  double              
B         2420000x16            154880000  int32

A= 800.090909093618 800.181818187237 800.272727280855 800.363636374474 800.454545468092 800.545454561710 800.636363655329 800.727272748947 800.818181842566 ...

B= 0 0 44 0 7 16 0 31 3 0 12 0 0 3 0 0 0 0 0 0 0 0 36 0 0 28 0...

M= 800 0 0 44 800 0 7 16 800 0 31 3 800 0 12 0 800 0 3 0 801 0 0 0 801 0 0 0 801 0 36 0 801 0 28 0...

It is rounding A with 0 digits

That is what I thought... Concatenating types like this will cause MATLAB to make M into an int32

M = [A,double(B)]

Yes it works now, I just started ti use matlab and now I think I need to learn about class of variables, thanks
