This CD contains symbols for the construction of matrices from lists.

## list_to_vector

Description:

This symbol denotes a binary function. Its first argument must be a ring R, its second argument must be list L with entries belonging to the ring R, up to ring1.expression. When applied to R and L it represents the vector of the same length as the list L whose i-th coordinate is L[i] (or ring1.expression(L[i])).

## list_to_matrix

Description:

This symbol denotes a binary function. Its first argument must be a ring R, its second argument must be list L of lists of equal lengths whose entries belong to the ring R, up to ring1.expression. When applied to R and L it represents the matrix whose i,j entry consists of the j-th entry from the list L[i]. In particular, the matrix has length(L) rows and length(L[1]) columns.
