I have a matrix:
A= [0 80 -100 0 1 0 1 0 1 0 1 ;...
0 0 0 0 1 0 1 1 0 1 0 ;...
-100 0 0 0 1 1 0 0 1 0 1 ;...
-100 100 0 0 1 1 0 1 0 1 0 ;...
100 0 -100 1 0 0 1 0 1 0 1 ;...
100 0 0 1 0 0 1 1 0 1 0 ;...
0 0 0 1 0 1 0 0 1 0 1 ;...
0 100 0 1 0 1 0 1 0 1 0 ]
Now i need to make a function if i type:
0 1 0 1 0 1 0 1
then it will show the corresponding total row. so, it'll show:
0 80 -100 0 1 0 1 0 1 0 1
But i don't know how to do. Can anyone please help me?

The result you want is simply the first row of ‘A’.
Is the argument vector you want to enter in your function some sort of code that the function has to interpret?

tofind = [0, 1, 1, 0, 0, 1, 0, 1];
found = A(ismember(A(:, 4:11), tofind, 'rows'), :)
will return all the rows of A whose columns 4 to 11 match tofind.
