Pull request overview
This PR adds consistent return behavior to matrix row operation helper functions. The changes ensure that both functions a and m return the matrix in all code paths, including early returns when validation fails.
- Modified functions
aandmto return the matrix parameter in early return conditions - Added explicit return statements after the matrix modification operations

The function name m is extremely cryptic and unclear. Based on its usage (replacing module.rowMult), this function performs row multiplication operations on a matrix. Consider renaming it to something more descriptive like row_mult or _row_mult (if intended to be private) to improve code readability and maintainability.

This function lacks a docstring explaining its purpose, parameters, and return value. Consider adding documentation such as: what the function does (adds a multiple of one row to another), what the parameters represent (a: matrix, b: source row index, c: target row index, d: scalar multiplier), and what it returns (the modified matrix).

The parameter name a shadows the function name a, which reduces code clarity. Additionally, using single-letter parameter names makes the code harder to understand. Consider renaming the parameters to be more descriptive, such as matrix, source_row_idx, target_row_idx, and scalar.

The function name a is extremely cryptic and unclear. Based on its usage (replacing module.rowAdd), this function performs row addition operations on a matrix. Consider renaming it to something more descriptive like row_add or _row_add (if intended to be private) to improve code readability and maintainability.
