# Source Notes: Provenance and Use

This file records the origin, publication status, and intended project use of
the optional source-note PDFs linked from `SOURCE_LINKS.md`.

## Provenance

The four PDFs were written and illustrated by Ron Fredericks while studying
courses taught by Mike X Cohen. They include Ron's personal course work,
experiments, notes, code completion, figures, and explanations. The documents
credit Mike X Cohen and identify the related courses and external sources
within their opening pages and lesson sections.

| PDF | Author metadata | Pages |
| --- | --- | ---: |
| `MasterMATLABGuidedProblems_CourseNotes.pdf` | Ron Fredericks | 253 |
| `MasterTheFourierTransformMATLABPython.pdf` | Ron Fredericks | 104 |
| `SignalProcessingProblemsMATLABPython.pdf` | Ron Fredericks | 126 |
| `Incomplete linear algebra3.pdf` | Ron Fredericks | 145 |

The documents are optional technical reference material for this project and
are not included in the portable ZIP.

## Publication Status

These notes have previously been published for free download on
[BiophysicsLab.com](https://www.biophysicslab.com/). Ron Fredericks is the
publisher of this project package; Mike X Cohen remains acknowledged as the
instructor and source-course author.

The completed project will be shared with
[Mike X Cohen](http://sincxpress.com/) for review, to invite any concerns,
corrections, suggestions, or possible participation in developing this model
for using established coursework with AI.

The project links to the established public pages instead of redistributing a
second copy of the PDFs. Their existing course attribution should remain
visible on those pages and within the documents.

## AI Use

Language models may use the PDFs as project-local reference material. They
should:

- Retrieve relevant sections through `MATLAB_REFERENCE_INDEX.md`.
- Preserve attribution when discussing a distinctive method.
- Avoid presenting course-derived material as newly authored by the model.
- Verify current MATLAB APIs separately because the notes reflect earlier
  MATLAB releases.
- Avoid reproducing large portions of the notes outside the project without
  confirming the intended publication terms.

## Process-Name Provenance

Ron Fredericks used **Cycles of Efficiency™** and a lens-shaped process visual
in a one-page Embedded Components, Inc. brochure titled *LectureMaker Web
Communication and Demonstration Service*. The surviving PDF reports a 2005
creation date in its metadata and shows multiple media, publishing, and
audience inputs converging through the named lens into reusable presentation,
transcript, blog, and attendance outputs.

The historical brochure is retained by Ron as provenance and is not included
in this portable project. A later public use of the term remains visible on
[LectureMaker.com](https://www.lecturemaker.com/products_services/cross-domain-video-platform/video-hosting/).
These records document historical usage; they are not presented as a legal
opinion about trademark ownership or registration.
