Function tropical_gemm_portable 

pub unsafe fn tropical_gemm_portable<T: TropicalSemiring>(
    m: usize,
    n: usize,
    k: usize,
    a: *const T::Scalar,
    lda: usize,
    trans_a: Transpose,

Tropical GEMM: C = A ⊗ B

Computes C[i,j] = ⊕_k (A[i,k] ⊗ B[k,j])

This is a portable (non-SIMD) implementation using BLIS-style blocking for cache efficiency.

Parameters

• m: Number of rows in A and C
• n: Number of columns in B and C
• k: Number of columns in A / rows in B
• a: Pointer to matrix A data
• lda: Leading dimension of A
• trans_a: Whether A is transposed
• b: Pointer to matrix B data
• ldb: Leading dimension of B
• trans_b: Whether B is transposed
• c: Pointer to matrix C data (output)
• ldc: Leading dimension of C

Safety

• All pointers must be valid for the specified dimensions
• Memory regions must not overlap inappropriately
