Summary by cubic

Adds Assignment A01 for student 40240378: a Python solution using numpy to build and classify special matrices and to demonstrate dimension errors. Adds README files and reflection, organized under the corrected submission folder layout.

• New Features

  • python/matrizes_tipos.py (T1–T4): creates zeros/identity/diagonal/triangular/symmetric matrices, reports shapes and element [2,3], classifies matrices, and shows errors for incompatible sums/products.
  • Classification uses np.allclose, np.eye, np.diag, np.triu, and np.tril.
  • 01/README.md with run steps and file map; reflexao.md covers identity matrix multi-class membership and a brief Python vs JS comparison.

• Refactors

  • Corrected folder structure to match the submission schema; added .gitkeep and a student-level assignments/submissions/40240378/README.md.

^{Written for commit 5b1a3db. Summary will update on new commits.}

Since this is your first cubic review, here's how it works:

• cubic automatically reviews your code and comments on bugs and improvements
• Teach cubic by replying to its comments. cubic learns from your replies and gets better over time
• Add one-off context when rerunning by tagging @cubic-dev-ai with guidance or docs links (including llms.txt)
• Ask questions if you need clarification on any suggestion

still to early for that, you should have waited for my go ahead

@Delcio1760 you have a coding error in this line, probably a missing line
