Can you help me? I wanted to solve this problem but I faced an error.

Write a random row vector x of size 1x10000. Find out the number of the elements of x that are below 0.2. Use a for loop for this.

-------

% generate a random row vector x of size 1x10000 and the number of the elements of x that are below 0.2
% assign x with 10000 random numbers
x = rand(10000,1);
% assign count with 0
count = 0;
% loop runs for 1 to 10000
% check the number is less than 0.2
% increment count by 1
for i = 1:10000
    if(x(i) < 0.2)
        count = count + 1;
    end
end
count
count = 1980

----------

Error using count

Not enough input arguments.

Your code works. You probably made that script called count.m or else you have another m-file in the folder, or on the search path, that is called count.m. Either rename your variable to theCount or rename your m-file to something else.
