dsh-linalg: DeepSeek Harness Linear Algebra Toolbox

dsh-linalg is a linear algebra toolbox for DeepSeek Harness, designed to address numerical errors that arise in large-model operations such as matrix multiplication and determinant computation. The plugin provides zero-dependency local exact arithmetic and supports capabilities such as matrix operations, solving linear systems, eigenvalue decomposition, and vector operations. After installation, users can configure the matrix dimension and the number of decimal places to retain via a configuration file. The plugin employs algorithms such as Gaussian elimination and the cyclic Jacobi method, using tolerance settings to ensure stable results.
