Hi,
t(a*t(b))
# [,1] [,2]
#[1,] 1 8
#[2,] 2 10
#[3,] 3 12
A.K.
Hello eveybody,
I have a vector a and a matrix b :
> a
[1] 1 2
> b
[,1] [,2]
[1,] 1 4
[2,] 2 5
[3,] 3 6
With simple multiplication I get :
> a * b
[,1] [,2]
[1,] 1 8
[2,] 4 5
[3,] 3 12
I would like to have that :
[,1] [,2]
[1,] 1 8
[2,] 2 10
[3,] 3 12
Fo now I use replicate bu I would like to do this in a simple way.
Do you have a solution ?
Thank you in advance
