I want to set
(1,1)
,(2,1)
,(3,3)
element of matrix A
to be 1.
In python I can do something like.
A=zeros(Int,4,4)
A[[1,2,3],[1,1,3]]=1
This does not work. What is the equivalent in Julia?
The following works (although a for
loop likely will be more efficient).
A[CartesianIndex.([(1,1), (2,1), (3,3)])] .= 1
