Table 2 shows the time required to access a matrix element when the indices are local variables, for
example, matrix[m1,m2]. The data shows that it takes slightly longer to access an element with
variable indices, but the overhead for indirect access is about the same, at a mean of 5.8 mS.

Table 3 shows the mean time required to access each element of matrices of various sizes. Element
indices are local variables, and the elements were accessed by value, for example, matrix[m1,m2].
