I copied porter stemmer code from the Github . The error is NOT ENOUGH INPUT ARGUMENTS.

FUNCTION CODE: ERROR IN THE 3RD LINE

function stem = porterdupe(instring)
global j;
b = instring;
k = length(b);
k0 = 1;
j = k;
% With this if statement, strings of length 1 or 2 don't go through the
% stemming process. Remove this conditional to match the published
% algorithm.
stem = b;
if k > 2
    % Output displays per step are commented out.
    %disp(sprintf('Word to stem: %s', b));
    x = step1ab(b, k, k0);
    %disp(sprintf('Steps 1A and B yield: %s', x{1}));
    x = step1c(x{1}, x{2}, k0);
    %disp(sprintf('Step 1C yields: %s', x{1}));
    x = step2(x{1}, x{2}, k0);
    %disp(sprintf('Step 2 yields: %s', x{1}));
    x = step3(x{1}, x{2}, k0);
    %disp(sprintf('Step 3 yields: %s', x{1}));
    x = step4(x{1}, x{2}, k0);
    %disp(sprintf('Step 4 yields: %s', x{1}));
    x = step5(x{1}, x{2}, k0);
    %disp(sprintf('Step 5 yields: %s', x{1}));
    stem = x{1};
end
end

You cannot run the code by clicking on Run or by using the menus to run it. You need to go to the command line and type in porterdupe and follow it by the string you want to process. For example,

porterdupe('hey there this is a string')
