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.

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?

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))));
