+function [p] = partition_delta(a, b, delta)
+  ## Partition the interval [a,b] into subintervals of length delta. We
+  ## do not require that a<b.
+  ##
+  ## INPUTS:
+  ##
+  ##   * ``a`` - The "left" endpoint of the interval to partition.
+  ##
+  ##   * ``b`` - The "right" endpoint of the interval to partition.
+  ##
+  ##   * ``delta`` - The length of the subintervals. 
+  ##
+  ## OUTPUTS:
+  ##
+  ##   * ``p`` - The resulting partition, as a vector of length (b-a)/delta.
