a
a =
1 2 3 4 5 6 7 8 9 10
>> b
b =
0 0 0 0 0
0 0 0 0 0
>> b(1,:)=a(0:4) ??? Subscript indices must either be real positive integers or logicals.

The error message is descriptive:
Subscript indices must either be real positive integers or logicals.
Using "0:4" is not "positive", because Matlab's indexing is 1-based:
b(1, :) = a(1:5)
