Index in position 1 is invalid. Array indices must be positive integers or logical values ERROR

hello ,

I try to create a matrix in which every element must have the same column sum of another matrix.

Specifically , i have this matrix :

0.9748 1

0.9748 1

0.5416 0.2996

and i want to create that matrix

0.9748+0.9748+0.5416 1+1+0.2996

0.9748+0.9748+0.5416 1+1+0.2996

0.9748+0.9748+0.5416 1+1+0.2996

i use this command :

second_term_denominator_2(j,i)=second_term_denominator_1(sum(second_term_denominator_1,i),i)

and it gives this error :

Index in position 1 is invalid. Array indices must

be positive integers or logical values.

Error in UNIFAC (line 67)

second_term_denominator_2(j,i)=second_term_denominator_1(sum(second_term_denominator_1,i),i)

I have attached the full folder of the code. I would be very gratefull if anyone could help me

hello.

you can use iteration like this

a =[ 0.9748  1;
0.9748  1;
0.5416   0.2996]
[x , y]  = size(a);
for(i = 1:x)
     for(j = 1:y)
          second_term_denominator_2(i,j) = sum(a(:,j));
     end
end
