matrix one [18 1 0 0 0;15 1 0 1 0;20 0 0 0 1]
matrix two [30 1 0 0 0;20 1 0 1 0;50 0 1 0 0]
matrix three [10 1 0 1 0;20 1 0 0 0;40 0 0 1 0]

...the new matrix i want consists of [18 1 0 0 0;30 1 0 0 0;20 1 0 0 0]

I do not see the relation between the three input arrays and the output. Please explain the procedure with all required details. Do not use explanations as "matrix one", but the valid Matlab syntax like "A= [...]". It is unclear in which format you store the 500 matrices, but this detail matters.

your_mat = [18 1 0 0 0;...
    15 1 0 1 0;...
    20 0 0 0 1];
idxFun = @(x) find(ismember(x(:,2:end),[1 0 0 0],'rows'));
your_row = your_mat(idxFun(your_mat),:);
