Hi,

I am trying to compute a matrix which 'matches' certain values in another matrix.

Here is where we start. The numbers in columns 1 and 2 which are also in the same row, need to be added together. For the first row, the number 1 needs to pull out the value 10 from MatrixB and add it with the number 2 which is 20. Thus giving us 30.

MatrixA

These are the values that need to be extracted. MatrixB

Now this is the plot twist and where I am stuck. The value 30 needs to be divided by 5 because there were values 1 and 2 in Matrix A. In MatrixC, the value next to 1 and 2 is 5.

Here is another example to ensure I get my question across. Numbers 2 and 3 (row 3, columns 1 and 2) will extract the values 20 and 30 which will make 50, this 50 needs to be divided by 7, which will give us 7.1428.

MatrixC
