---% Matrix creation
-
-    matrix: List List R -> %
-      ++ \spad{matrix(l)} converts the list of lists l to a matrix, where the
-      ++ list of lists is viewed as a list of the rows of the matrix.

---% Predicates
-
-    square?  : % -> Boolean
-      ++ \spad{square?(m)} returns true if m is a square matrix (i.e. if m
-      ++ has the same number of rows as columns) and false otherwise.
-    diagonal?: % -> Boolean
-      ++ \spad{diagonal?(m)} returns true if the matrix m is square and diagonal
-      ++ (i.e. all entries of m not on the diagonal are zero) and false
-      ++ otherwise.
-    symmetric?: % -> Boolean
-      ++ \spad{symmetric?(m)} returns true if the matrix m is square and
-      ++ symmetric (i.e. \spad{m[i,j] = m[j,i]} for all \spad{i} and j) and
-      ++ false otherwise.
-    antisymmetric?: % -> Boolean
-      ++ \spad{antisymmetric?(m)} returns true if the matrix m is square and
-      ++ antisymmetric (i.e. \spad{m[i,j] = -m[j,i]} for all \spad{i} and j)
-      ++ and false otherwise.
