>> find_stems Error using cellfun Non-scalar in Uniform output, at index 1, output 1. Set 'UniformOutput' to false.

Error in find_stems (line 3) results = cellfun(@porterdupe, t); ---------------------------------------------------------------------

code: find_stems.m function results = find_stems() t = simple(); results = cellfun(porterdupe, t);

--------------------------------------------- code: porterdupe.m

function [stem] = porterdupe(y) t = y; global j; b = t; 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 = simple(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

% cons(j) is TRUE = b[j] is a consonant.

function c = cons(i, b, k0) c = true; switch(b(i)) case {'a', 'e', 'i', 'o', 'u'} c = false; case 'y' if i == k0 c = true; else c = ~cons(i - 1, b, k0); end end end
