sym(zeros(4, 1));
is showing an error "Subscript indices must either be real positive integers or logicals". What may be the reason behind this error? How it can be resolved ??

Try
A = zeros(4,1) ;
B = sym(A) ;
What version you are using?

Is it possible that you have defined a variable named sym, and you are trying to index into that? What does the command
which sym
give?
If that gives a variable name, that's presumably the problem. Remember not to use variable names that are MATLAB keywords.
