function [ LargestMatrix ] = GetLargestMatrix( InputMatrix, largestIDs, instanceIDs )

%GetLargestMatrix 

%   Kind of a strange function. You feed this the IDs of the rows that you

%   want to use as 'largest area border of that slice' and it will get

%   those rows for you in order. Testing with another function confirmed

%   this is the same order as the Y matrix we're using, so no need to try

%   and reorder the data. 

%get the rows of the instance IDs that match the instance IDs to generate

%Patrick's segmentations (same order)

for i = 1:length(largestIDs)

   largestRows(i) = find(largestIDs(i) == instanceIDs); 

end

largestRows = largestRows';

LargestMatrix = InputMatrix(largestRows,:);
