>> enz=[];
>> enz=zeros(8,3);
>> for ii=1:14
for jj=1:3
match=ismember(file1,rxn)
if match(ii)==1
enz(ii,jj)=rxn(ii,jj)
end
end
end
rxn is 14x3, and file1 is 8x1 . i found the contents of the file1 in rxn and now i'm going to copy the whole contents of related rows(the rows that contains the same contents) in rxn to a new matrix, which should creat a 8x3 matrix, but i cant shape this matrix

You need to use the 'rows' option of ismember to find matching rows. Something like, (untested)
matchingRows = ismember(file1, rxn, 'rows');
enz = rxn(matchingRows, :);
