Corresponding vector values to array values

I have an array 51 by 51 and I have 6 vectors where the vector elements are the dimensions of the array. How i correspoding the vector values to the array values?

I attach an excel file with the array and the vectors.

For your input vector

1  31  11  40  34  46  19  25  24  0  0 

what would you expect the result to be? Matrix(31,11), Matrix(40,34), Matrix(46,19), and Matrix(25,24) ?

the result o matrix(1-31),(31-11),(11-40) etc.

I tried with it ,to no avail

[row,col]=size(route);
cost=0;
total=0;
for i=1:row
   
    for j=1:col
      A=route(i,j);
     B=route(i,j);
     cost=array(A,B);
      A=B;
     B=B+1;
     total=total+cost;
        
    end
end

Your matrix is 51 x 51, so it is not immediately clear what matrix(1-31),(31-11) might mean. Are you looking for matrix(1,31) then matrix(31,11) then matrix(11,40) and so on? So a path through the matrix?

[giorgos kivides]

for example. when it reads the numbers 1-47 of vector, it will go to the array in row 1 and column 47 and read the number.

Vector = [1  31  11  40  34  46  19  25  24  0  0];

nodes = Vector(Vector ~= 0);
total = sum(Matrix(sub2ind(size(Matrix), nodes(1:end-1), nodes(2:end))));

Thanks a lot..
