**ForEig**: A Fortran library for eigenvalue and eigenvector calculations.

## Usage

```Fortran

use foreig, only: eig

call eig(A, eig_vec, eig_val ,method='ggev') ! method='syev' .or. 'geev' .or. 'ggev'

```

## fpm dependency

If you want to use `ForEig` as a dependency in your own fpm project,

you can easily include it by adding the following line to your `fpm.toml` file:

```toml

[dependencies]

forieig = {git="https://github.com/gha3mi/forieig.git"}

```
