Function and Subfunction problem

I have a question. Somehow I cant make the following functions work I know that I need in each n = length(x), but how can I do that?

function [gm,ra,hm] = arm_prop(x)
n = lenght(x);                      %send it to next funtion, but how
gm = gmean (n,x);
ra = rms (n,x);
hm = hmean (n,x);
end 

function gm = gmean (n,x)
prd = 1;
    for i = 1:n
        prd = prd * x(i); 
    end 
end

% A SUM MEANS I NEED A FOR LOOP!

function ra = rms (n,x)
sm = 0; %Initialize sum
for i = 1:n;
    sm = sm + x(i)^2;
end
ra = sqrt(sm/n);
end 

% Its again a Sum
function hm = hmean (n,x)
sm = 0;
for i = 1:n;
    sm = sm/x(i);    
end 
hm = n/sm
end

What's the problem? Any error messages?

• there is a typo in &nbsp n = lenght(x);
• gm is not assigned a value in &nbsp gmean

You have

n = lenght(x);                      %send it to next funtion, but how

You need

n = length(x);                      %send it to next funtion, but how

lenght vs length
