For example matrix: I would like to sum elements … WebIf you want the sum of $i$-th row then it is in general $\sum_{j ∈ J} x_{ij}$ which is variant of $\sum (x_{ij}: j ∈ J)$ and depends on $i$. In case that $J = \{1, …, n\}$, then $\sum_{j = 1}^n x_{ij}$ is used as a shortcut for $\sum_{j ∈ \{1, …, n\}} x_{ij}$.

WebTogether, these facts show us that tr ( A B) is equivalent to the sum of all the elements in A. More explicitly: tr ( A B) = ∑ i = 1 n ∑ j = 1 n A i j. With multi-index notation, this can be equivalently expressed as: tr ( A B) = ∑ 1 ≤ i ≤ j ≤ n i, j n A i j. Or more simply: ∑ i, j A i j. WebMar 31, 2016 · View Full Report Card.

The following is an example of this:
WebThe original function was written by Terry Therneau, but this is a new implementation using hashing that is much faster for large matrices. To sum over all the rows of a matrix (i.e., a single group) use colSums, which should be even faster. For integer arguments, over/underflow in forming the sum results in NA.
