dgemm_

✓ use blas_sys::c::dgemm_;

Calls BLAS dgemm_ to multiply two matrices.

use blas_sys::c::dgemm_; fn main() { // Example: C = alpha * A * B + beta * C let (m, n, k) = (2, 2, 2); let a = vec![1.0, 2.0, 3.0, 4.0]; let b = vec![5.0, 6.0, 7.0, 8.0]; let mut c = vec![0.0; 4]; let alpha = 1.0; let beta = 0.0; unsafe { dgemm_( b"N" as *const u8 as *const i8, b"N" as *const u8 as *const i8, &m, &n, &k, &alpha, a.as_ptr(), &m, b.as_ptr(), &k, &beta, c.as_mut_ptr(), &m, ); } println!("{:?}", c); }

Debug

Known issues

gotchaRequires a system BLAS library (e.g., OpenBLAS, Intel MKL) to be installed.

fix

Install a BLAS library or use a Rust-native alternative like `ndarray-linalg`.
