Containg the especific number in the vector

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)

Please follow the prefered answer @Madhan ravi sir

Still if you are learning, you can look at the following

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

Perfectly Madhan,

it works!!!

Thank you very much for attention.
