Not enough input arguments.

L = data(:,3); %this is the length/value of each item
for k = 1:length(P)
   item.test(k) = tolerance(item.cat(k),L(k));
end 
%%
%functions
function [fit] = tolerance(category,value)
if category == 1
    if value>=25.1 && value<=26.05
        fit = 55;
    else 
        fit = 99;
    end 
elseif category == 2
        if value>=25.92 && value<=26.08
        fit = 55;
    else 
        fit = 99;
        end

    if value>=25.88 && value<=26.12
        fit = 55;

I have a strcuture field called (item.cat) which is the category of 4 items (1-4) and the user defined function I made is supposed to go through all of the values in the structure field and determine if each item fits the specific tolerences based on its category. However I keep getting the ERROR

Not enough input arguments.

Error in tolerance (line 2)

if category == 1

what does it mean by not enough inputs? I'm trying to determine if the value in the matrix is in category 1,2,3 or 4 so wouldn't the only input be the category which in this case is the structure field 'item.cat'?

If that error message is complete, then you are attempting to run your tolerance function by itself instead of running your script.

Ok thanks!
