Good way to compare two cell arrays???

[Darin]

Hello,

Your advice is needed to help figure out an eloquent solution to compare two cell arrays (that contain strings). The first cell array (files) needs to be shrunk down whenever it exists in the second array (finishedfiles). The final shrunken down array is called newfiles. Is there a better way to do this???

count2= 0;
for i = 1:numel(files)

count = 0;
for j = 1:numel(finishedfiles)
if strcmp(files{i},finishedfiles{j})
count=1;
break;
end
end

if count == 0;
count2 = count2+1;
newfiles{count2} = files{i};
end

end

not 100% sure, but i think this should do what you want

clc
clear all

files={'file1';'file2';'file3'};
finishedfiles={'file3';'file2'};

a=repmat(files,size(finishedfiles));
b=sort(repmat(finishedfiles,size(files)));

c=(strcmp(a,b));

d=reshape(c,size(files,1),size(c,1)/size(files,1));

newfiles=files(~logical(sum(d,2)))

Thanks! Turns out i could compress those 14 lines into 1 line.....

files = setdiff(files,finishedfiles);

good times :)
