First Thanks to Bonnie (where ever she is)for the nested arrays hint. It turns out that there is a mathcad script for extracting an array of 1x1 vectors. It is called UnStack. I found it somewhere here on the collaboratory.
Next Question. Does the programming in Mathcad support vectors and arrays of vectors. If so is there a good example of passing vectors and arrays as in and out parameters? Thanks up front.
Incidently I am attaching the Mathcad script UnStack for those that are interested.
