Modern Fortran Edition of the DVODE ODE Solver.
**THIS IS A WORK IN PROGRESS!**

### Documentation
The latest API documentation can be found [here](https://jacobwilliams.github.io/dvode/). This was generated from the source code using [FORD](https://github.com/Fortran-FOSS-Programmers/ford) (i.e. by running `ford ford.md`).
### Compiling
The library can be compiled with recent versions the Intel Fortran Compiler and GFortran (and presumably any other Fortran compiler that supports modern standards).
A `fpm.toml` file is provided for compiling dvode with the [Fortran Package Manager](https://github.com/fortran-lang/fpm). For example, to build:
```
fpm build --profile release
```
By default, the library is built with double precision (`real64`) real values. Explicitly specifying the real kind can be done using the following processor flags:
Preprocessor flag | Kind | Number of bytes
----------------- | ----- | ---------------
`REAL32` | `real(kind=real32)` | 4
`REAL64` | `real(kind=real64)` | 8
`REAL128` | `real(kind=real128)` | 16
For example, to build a single precision version of the library, use:
```
fpm build --profile release --flag "-DREAL32"
```
To run the unit tests:
```
fpm test --profile release
```
To use `dvode` within your fpm project, add the following to your `fpm.toml` file:
```toml
[dependencies]
dvode = { git="https://github.com/jacobwilliams/dvode.git" }
```
or, to use a specific version:
```toml
[dependencies]
dvode = { git="https://github.com/jacobwilliams/dvode.git", tag = "1.0.0" }
```
The library requires some [BLAS](https://netlib.org/blas/) routines, which are included. However, the user may also choose to link to an external BLAS library. This can be done by using the `HAS_BLAS` compiler directive. For example:
```
fpm build --compiler gfortran --flag "-DHAS_BLAS -lblas"
```
However, note that an external BLAS can only be used if the library is compiled with double precision (`real64`) reals.
