Compute Accumulated Commute Time Matrix from Transition Matrix
Arguments
- T_mat
A square transition matrix (symmetric, row-normalized).
Value
A matrix of accumulated commute times between all pairs of nodes.
Details
Computes the accumulated commute time (ACT) matrix from a normalized transition matrix.
This is used as a basis for diffusion-based distances and pseudotime inference.
Examples
mat <- matrix(runif(100), nrow = 10)
mat <- mat / rowSums(mat)
act <- acct(mat)
#> Error in acct(mat): could not find function "acct"
print(dim(act))
#> Error in print(dim(act)): object 'act' not found
