equal_unit_vec: check whether a vector is equal to a unit vector with the one...

In oslerinhealth/rewind: Reconstructing Etiology with Binary Decomposition

Description

This function is used in updating Q matrix if we constrain the updates within the identifiability assumption

Usage

equal_unit_vec(v, k)

Arguments

v	the vector (a binary vector)
k	the index that is being checked if v[k] is the only one in vector v. k must be smaller than or equal to the length of k

Value

TRUE if v = \mathbf{e}_k; FALSE otherwise.

Examples

 equal_unit_vec(c(1,0,0,0,0,0),1)
 equal_unit_vec(c(1,0,0,0,0,0),2)
 equal_unit_vec(c(0,0,2,0,0,0),3)
 equal_unit_vec(c(0,0,1,0,0,0),3)
