Walkthrough

Updates to educational course material for linear algebra (chapter 4), including corrections to mathematical examples involving null space bases and column space bases, alongside comprehensive reorganization of the coordinate system discussion section with renaming and restructured content presentation.

Changes

Cohort / File(s) Summary
Mathematical Example Corrections
projects/stae107g/kafli04.rst
Adjusted nilpotent example solution vector by adding a second component to the basis representation of Null(A), and updated a basis vector in the dálkrúm (column space) example from [2; 7; 1] to [2; 7; 12].
Coordinate System Content Reorganization
projects/stae107g/kafli04.rst
Restructured multiple sections covering coordinate concepts (hnita), including removal and reinsertion of content under renamed headings (e.g., "Hnitaskiptafylki" → "Hnit og hnitaskipti"), affecting documentation flow and section hierarchy without introducing new mathematical definitions.

⚠️ Potential issue | 🟠 Major

Fix section title underline length to valid RST heading syntax.

The underline under Hnit og hnitaskipti is too short for the title text, which can cause Sphinx/Docutils heading parsing warnings (and fail strict doc builds). Please extend the hyphen line to at least the title length.

Suggested fix
 Hnit og hnitaskipti

+-------------------

As per coding guidelines "For reStructuredText files: Check for proper use of RST syntax and Sphinx directives."

📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
