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?

That is what I thought... Concatenating types like this will cause MATLAB to make M into an int32
M = [A,double(B)]
