Crate lapack_inject 

lapack-inject

LAPACK compatible interface backed by Fortran LAPACK function pointers.

This crate allows you to use LAPACK functions while the actual computation is performed by Fortran LAPACK functions provided at runtime. This is useful for integrating with Python (scipy) or Julia (libblastrampoline) where Fortran LAPACK pointers are available.

Usage

use lapack_inject::register_dgesv_lp64;

// Register Fortran dgesv pointer (e.g., from scipy or Julia)
unsafe {
    let status = register_dgesv_lp64(dgesv_ptr);
    assert_eq!(status, 0);
}

// Now lapack_inject exports dgesv_ symbol that can be used by other crates

lapack-src/lapack-sys Compatibility

This crate exports a generated subset of Fortran-style LAPACK symbols such as dgesv_, dgetrf_, and dgesc2_. Register LP64 or ILP64 function pointers at runtime, and this crate provides those symbols to downstream crates that expect a LAPACK provider.

LAPACKE-style C entry points are exported for dgesv, dgetrf, dgetri, and dpotrf, including _64 variants and row-major layout handling.

Supported Functions

The generated Fortran surface supports:

• xGESV, xGETRF, xGETRS, xGETRI, xPOTRF
• xGESVD
• xGEQRF, real xORGQR, complex xUNGQR
• xTRTRS
• s/dSYEV, c/zHEEV
• xGEEV
• supplemental complete-pivoting LU routines xGETC2 and xGESC2

The default build keeps the consumer-facing Fortran symbols LP64-compatible. Register ILP64 host providers with the _ilp64 registration functions; do not enable the ilp64 feature just because the host provider is ILP64. The feature changes the consumer ABI too.

Re-exports

pub use fortran::*;

pub use lapacke::*;
