Description

Vector-To-Tensor Representation

Usage

vec2mat(vector, twice = FALSE)

Arguments

vector	A vector of size 6 storing the 6 unique components of a tensor.
twice	A boolean that says whether off-diagonal tensor elements were doubled in vector representation (default: FALSE).

Value

A 3x3 symmetric postive definite matrix as output tensor.

Examples

v <- seq_len(6L)
vec2mat(v)
