+    r"""Construct a Hadamard matrix of order `n` from a symmetric conference matrix
+    of order `n/2`.
+
+    The construction is described in Theorem 4.3.24 of [IS2006]_.
+    The symmetric conference matrices are obtained from
+    :func:`sage.combinat.matrices.hadamard_matrix.symmetric_conference_matrix`.
+
+    INPUT:
+
+    - ``n`` -- integer; the order of the matrix to be constructed
+    - ``existence`` -- boolean (default: ``False``); if ``True``, only check if
+      the matrix exists
+    - ``check`` -- boolean (default: ``True``); if ``True``, check that the matrix
+      is a Hadamard before returning
+
+    OUTPUT:
+
+    If ``existence=False``, returns the Hadamard matrix of order `n`. It raises
+    an error if no data is available to construct the matrix of the given order,
+    or if `n` does not satisfies the constraints.
+    If ``existence=True``, returns a boolean representing whether the matrix
+    can be constructed or not.
+
+    EXAMPLES:
+
+    By default the function returns the Hadamard matrix ::
+
+        sage: from sage.combinat.matrices.hadamard_matrix import hadamard_matrix_from_symmetric_conference_matrix
+        sage: hadamard_matrix_from_symmetric_conference_matrix(20)
+        20 x 20 dense matrix over Integer Ring...
+
+    If ``existence`` is set to True, the function returns True if the matrix exists,
+    False if the conference matrix does not exist, and Unknown if the conference
+    matrix cannot be constructed yet ::
+
+        sage: hadamard_matrix_from_symmetric_conference_matrix(12, existence=True)
+        True
