If the seq(5,205) was a typo, and should have been
seq(5,20,5), then what you're looking for is the outer
product of x and y:
x = seq(5,20,5)
y = seq(5,20,5)
x %o% y
[,1] [,2] [,3] [,4]
[1,] 25 50 75 100
[2,] 50 100 150 200
[3,] 75 150 225 300
[4,] 100 200 300 400

Hi guys:
Sorry if this question is very basic. I’m learning basic matrix and
vectors multiplication to develop a population matrix model for
plants. I’m trying to multiply the elements of two vectors (each of
the “x” values by each of the “y” values) to obtain a square matrix of
xy values.
f.e.
x
Sorry I just sent a message, but I forgot to say thanks for any
suggestion and help!!
