I currently have 2 sets of data and I am trying to find a match based off of it's name. For example in data1 it contains apple, banana, orange, pear,etc and data 2 contains apple-1, apple-2, apple-3, banana-1, banana-2, banana-3, orange, pear-1, pear-2, etc. Ultimately, I would like to write a script to match for example apple with apple-1, apple-2, apple-3 etc and print out the corresponding data:
Col 1 column 2
apple apple-1
apple apple-2
apple apple-3
banana banana-1
banana banana-2
banana banana-3
orange orange
pear pear-1
pear pear-2
I have the following code:
[nRows,~]=size (data2); % 6204x13 matrix
[nRows2,]=size (id); %258x1 matrix
temp2=data2.SAMPLEID;
temp3=id;
for i=2:nRows
temp4=strfind (id,data2.SAMPLEID{i});
ind= find(~isempty(temp4),1,'first');
for n=1:nRows2
sampleid{n,1}=temp3;
if ind ==1
% if ~isempty(ind{n});
sampleid{n,2}=temp2;
else
sampleid{n,2}=temp3;
end
end
temp3= id{i};
temp2=data2.SAMPLEID{i};
end

d1 = {'apple'; 'orange';'banana'; 'pear'}
d2 = {'apple-1'; 'pear-1'; 'apple-2';'banana-3'; 'orange'; 'apple-3'; 'banana-1';'banana-2'; 'pear-2'}
[v,iii] = sort(d2);
p = strcat(d1(1:end-1),{'|'});
p = strcat([p{:}],d1{end});
pp = regexp(d2,p,'match');
pp = cat(1,pp{:});
[~,ij] = ismember(pp,d1);
dd1 = d1(ij);
out = [dd1(iii),v]

d3 ={'red';'orange';'yellow';'green'}
d33=d3(ij)
color1 = d33(iii)

"Col 1", "column 2", "data1", "data 2", "data2", "id" - I've lost the overview.
nRows concerns the size of the array data2. But the loop for i=1:nRows affects data2.SAMPLEID{i}. Perhaps you want data2(i).SAMPLEID or data2{i}.SampleID.
You have explained ropughly, what you want to achieve and posted some code. It is hard to recognize the relation between these two information. What is the actual question? Does the code run? Do you get any errors or unwanted results?

Please post the line of code and a copy of the complete error message. There is no chance that we can guess the reason of the problem.
