Check the spelling of "function".

For every start of a loop you write in MATLAB you must "end it" with an "end". They come in pairs.

Now it looks like you did properly close your loop but you incorrectly wrote "funcion" instead of "function", that is where you error it actually coming from.

function vari = variance(a)
total = sum(a);
width = length(a);
avg = total/width;
v=0;
for c = 1 : legnth(a)
    v = v +(a(c)-avg)^2;
end

vari = v / (width-1);
end
