function k=next_prime(n)
while true;
n = n+1
for i in rng(2:n):
if mod(n,i) == 0
return k
#getting error

Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax error. To construct matrices, use brackets instead of parentheses.

MATLAB does not use colon as a statment separator or statement terminator. You should remove it from the end of your for line.
Note: when the first parameter to the rng() function is numeric, then the parameter must be a scalar, not a vector of integers.
Note: the rng() function always returns a structure that gives information about the internal state of the random number generator. The mod() function will not accept that structure as the second parameter to mod().
