Description Usage Arguments Value Note Author(s) Examples

Transforms a list of scalars, vectors, or matrices into a simplified structure with one additional dimension (i.e. a vector, matrix, or 3D array).

1	simplifyList(L)

`L`	List to be transformed. All elements of `L` must share the same type, length, dimension(s) and name(s). See the return value for supported element types.

The returned type depends on the type of the elements of L.

scalar case: If each element of L is a scalar, the result is a vector of length length(L).
vector case: If each element of L is a vector, the result is a matrix. The number of rows equals length(L) and the number of columns is determined by the length of the vectors, i.e. length(L[[1]]).
matrix case: If each element of L is a matrix, the result is an array with 3 dimensions. The length of dimension 1 equals the number of the matrices' rows, the length of dimension 2 equals the number of the matrices' columns, and the length of the 3rd dimension is length(L).

An error is generated if the restrictions with respect to the elements of L are not met.
