Question

Does anybody know how to solve

removing duplicates – ** only when the duplicates occur in sequence

in Octave? The accepted solution is using diff.

Matlab’s diff seems to behave differently than the Octave’s one and doesn’t accept characters.

Any idea is appreciated.

Answer 1

You can convert the characters to their ASCII codes, then run the solution as given:

a = {'d' 'f' 'a' 'g' 'g' 'w' 'a' 'h'};
aa = cellfun(@(c) c-0, a);             %# convert to ASCII

idx = find(diff(aa) == 0);
a([idx idx+1]) = [];
