plot function Too many input arguments.

function [output_noise] = uniformnoise
range=0.003;
size=3000;
output_noise(1:size)=0;

for i=1 : size
    output_noise(i) = (rem(rand()*100,(2*range+1)) - range) * 0.0001;
end

i=1:1:size;
plot(i, output_noise)  <-

end

////////// what happen?

Just before plot(), put this line:

which -all plot

tell us what shows up in the command window.

This function works fine and nothing's wrong, it worked here correctly. The output_noise is (1 by 3000) and its maximum is ~ 1 e-4 and min ~ -2e-7.

But your code doesn't have the ( <- ) in the line:

   plot(i, output_noise)  <-

.. am I right? Delete this or put % before it as in:

   plot(i, output_noise) %  <-

This is the only change I've made :)
