>> 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);
