Description

The session aimed to analyze the conditions of lower triangular matrices and resolve programming errors in matrix manipulation using SymPy.

Conducted a mathematical analysis of the condition numbers ( \text{Cond}_\infty ) and ( \text{Cond}_2 ) for lower triangular matrices as ( n ) increases, demonstrating their tendency towards infinity.
Presented results for matrix ( A ) with ( n=3 ), including its inverse and infinity norms.
Addressed a SymPy error related to matrix row assignment, providing corrected code to ensure compatibility with SymPy’s matrix objects and proper application of a lower triangular mask.
Analyzed the sensitivity of matrix ( A ) through its condition number and explored a lower bound for ( \text{Cond}_\infty(A) ) using a singular matrix ( B ).
Simplified the symbolic representation of matrix differences for further analysis.

Successfully demonstrated the increasing condition numbers for triangular matrices as ( n ) increases.
Resolved SymPy matrix manipulation errors, enhancing code reliability.
Provided a comprehensive analysis of matrix ( A ) and its numerical sensitivity.

Further exploration of symbolic matrix differences and their impact on condition numbers.
Additional analysis on the properties of the infinity norm with practical examples.
