Summary

This PR improves the documentation quality with several focused fixes and enhancements:

README.md fixes:

  • Fixed inconsistent initial condition in scalar equation example (stated y(0)=0.0 but code used y0=1.0)
  • Corrected Jacobian matrix syntax in pendulum example to use proper Julia matrix syntax ([[a -1]; [cos(y[1]) a]])

Added comprehensive docstrings:

  • dassl() constructor: Documents algorithm parameters and usage
  • dasslSolve(): Complete documentation with arguments, keyword arguments, return values, and examples for both scalar and vector cases
  • dasslIterator(): Documents the iterator interface with practical usage example

All docstrings follow Julia documentation standards with proper formatting, cross-references, and working code examples.

Changes Made

  1. README.md (2 fixes):

    • Line 41: Changed "initial data y(0)=0.0" → "y(0)=1.0" to match the code
    • Line 129: Fixed Jacobian matrix syntax from [[a,cos(y[1])] [-1,a]][[a -1]; [cos(y[1]) a]]
  2. src/common.jl:

    • Added 25-line docstring for dassl() constructor
  3. src/DASSL.jl:

    • Added 37-line docstring for dasslIterator()
    • Added 52-line docstring for dasslSolve()

Impact

These changes improve documentation discoverability and usability without affecting any code behavior. Users will now have proper documentation when using ?dassl, ?dasslSolve, or ?dasslIterator in the REPL.

🤖 Generated with Claude Code

Fixed several documentation issues:
- Corrected initial condition in README example (y(0)=1.0 matches y0=1.0)
- Fixed Jacobian matrix syntax in pendulum example (proper Julia matrix syntax)
- Added comprehensive docstrings for main API functions:
  - dassl(): Algorithm constructor with parameter documentation
  - dasslSolve(): Main solver function with examples
  - dasslIterator(): Iterator interface with usage example
- Improved clarity and completeness of function documentation

All docstrings follow Julia documentation standards with argument
descriptions, keyword arguments, return values, and working examples.
