Array indices must be positive integers or logical values.

Background: Write the function SPP of the shortest path problem from starting point 1 to end point n, based on Dijkstra's idea of shortest path

n: the number of nodes, the node number is 1,2... ,n

t is the matrix where t(I,j) represents the distance from node I to the directly connected edges of node j. If there is no directly connected edge from I to j, then T of I,j is equal to Inf of infinity.

and when I write:

f(i)=min{f(j)+tij};

It shows an error: "Array indices must be positive integers or logical values."

%if true
 f(i)=min{f(j)+t(i,j)};
