r - How to generate a matrix with a sequence based on one m variable -


i have problem for loop matrix 1 variable m. how solve matrix loop?

[1 1/2 ... 1/(m+1),  1/2 1/3 ... 1/(m+2),  ... ... ...,  1/(m+1) 1/(m+2) ... 1/(2m+1)]

i generate on matlab code:

m = 10; m1 = repmat(1:m+1,1,m+1); m2 = reshape(m1,m+1,m+1); m3 = m2 + m2' - 1; m4 = 1./m3;

how can generate same code in r?

you can do:

m <- 4 <- matrix(,m+1, m+1) <- 1/(col(a)+row(a)-1) # > #           [,1]      [,2]      [,3]      [,4]      [,5] # [1,] 1.0000000 0.5000000 0.3333333 0.2500000 0.2000000 # [2,] 0.5000000 0.3333333 0.2500000 0.2000000 0.1666667 # [3,] 0.3333333 0.2500000 0.2000000 0.1666667 0.1428571 # [4,] 0.2500000 0.2000000 0.1666667 0.1428571 0.1250000 # [5,] 0.2000000 0.1666667 0.1428571 0.1250000 0.1111111
