Detailed Description

Unit tests for GSL BLAS (Basic Linear Algebra Subprograms) operations.

This file contains unit tests for GSL-compatible BLAS operations including matrix-matrix and matrix-vector multiplications for both real and complex data types.

Test:

GSLBLASTest::DGEMM_NoTrans Tests double-precision general matrix-matrix multiplication without transposition: \(\mathbf{C} = \alpha \mathbf{A} \mathbf{B} + \beta \mathbf{C}\) with \(\alpha = 1\) and \(\beta = 0\). Verifies correct computation of matrix product for non-square matrices.

Test:

GSLBLASTest::DGEMM_WithBeta Tests matrix-matrix multiplication with non-zero \(\beta\) coefficient. Verifies that the operation \(\mathbf{C} = \alpha \mathbf{A} \mathbf{B} + \beta \mathbf{C}\) correctly combines the matrix product with the existing matrix \(\mathbf{C}\).

Test:

GSLBLASTest::DGEMM_Transpose Tests matrix-matrix multiplication with transposed matrices. Verifies that \(\mathbf{C} = \mathbf{A}^T \mathbf{B}\) is computed correctly, including the case where \(\mathbf{A}^T\) and \(\mathbf{B}\) have compatible dimensions.

Test:

GSLBLASTest::DGEMV Tests double-precision general matrix-vector multiplication: \(\mathbf{y} = \alpha \mathbf{A} \mathbf{x} + \beta \mathbf{y}\). Verifies correct computation of matrix-vector product and combination with existing vector \(\mathbf{y}\).

Test:

GSLBLASTest::ZGEMM_Complex Tests complex matrix-matrix multiplication using double-precision complex numbers. Verifies that complex matrix products are computed correctly, including the identity matrix case \(\mathbf{I} \mathbf{I} = \mathbf{I}\).
