Description

Trying to append a matrix to a list, e.g.:

mat = matrix("1 2 3 6
              4 3 2 5
              1 1 2 4", rows=3, cols=4)
              
my_list = list()
my_list = append(my_list, mat)

seems not to work, and raises an error message.

An Error Occured : LanguageException -- Invalid Parameters : ERROR: test2.dml [line 6:0] -> my_list = append(my_list, mat) -- inputs to cbind must have same number of rows: input 1 rows: 0, input 2 rows: 3
