+    orthogonal polynomial transforms. The univariate algorithms have a runtime
+    complexity of O(n log n), while the multivariate algorithms are 2-normwise
+    backward stable with a runtime complexity of O(nd+1), where n is the
+    polynomial degree and d is the spatial dimension of the problem."""
