Create Diagonal Matrix From Vector
Given an input row or column vector, vec2diag returns a diagonal matrix with the input argument along the diagonal.
vec2diag(x)
x |
a row or column vector. |
Similar to the function diag, except that the input argument is always
treated as a vector of elements to place along the diagonal.
vec2diag(matrix(1:4, 1, 4)) vec2diag(matrix(1:4, 4, 1))
