Hi MATLAB Community,
I would to ask a help please,
my purpose in the follow code is counting, how many number greater 1 or equal (x>=1), and put in a variable the number of values greater 1.
The code are as follows:
Which is my mistake in the code?
Error message :
Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax error.
To construct matrices, use brackets instead of parentheses.
Thank you very much for attention

b = linspace(0,5,20);
n=0;
m=0;
for b = 1:n
if b(1,:n)>=0
n = n+1;
else
m=m+1;
end
end

No loops needed:
numbers_greater_than_one_or_equal = nnz(b>=1)
numbers_lesser_than_one = nnz(b<1)
