Correct results are obtained from matrix multiplications if a second index, always set to 1, is considered as inserted (for a column vector) after the variable index, or (for a row vector) before the variable index. Here are two examples, in which A is a 2 × 3 matrix, u is a column vector of dimension 3, and v is a row vector of dimension 2. Where the MATCH function is used to find the correct row to return from array, and the INDEX function returns the value at that array.. However, in this case we want to make the array variable, so that the range given to INDEX can be changed on the fly. We do this with the CHOOSE function: An indexed rate is an interest rate that is tied to a specific benchmark with rate changes based on the movement of the benchmark.
