diag3Darray-set: Define function to change the diagonal of array

In NeuralSens: Sensitivity Analysis of Neural Networks

Define function to change the diagonal of array

Description

Define function to change the diagonal of array

Usage

diag3Darray(x) <- value

Arguments

x	3D array whose diagonal must be c hanged
value	vector defining the new values of diagonal.

Details

The diagonal of a 3D array has been defined as those elements in positions c(int,int,int), i.e., the three digits are the same.

Value

array with all elements zero except the diagonal, with dimensions c(dim,dim,dim)

Examples

x <- array(1, dim = c(3,3,3))
diag3Darray(x) <- c(2,2,2)
x

#  [,1] [,2] [,3]
#  [1,]    2    1    1
#  [2,]    1    1    1
#  [3,]    1    1    1
