[Solved] Function returns quadratic matrix in R [closed]

by


You were almost there. you just had to specify n and return the right object at the end.

matrix_a = function(n) {
    A = matrix(data = 0, nrow = n, ncol = n) 
    for (i in 1:n) {
        for (j in 1:n) {
            if (i>=j) {A[i,j] = (i^2)} 
            if (i<j) {A[i,j] = (j^2)}
        }
    } 
    A
}

matrix_a(3)
#      [,1] [,2] [,3]
# [1,]    1    4    9
# [2,]    4    4    9
# [3,]    9    9    9
