iemmatrix - matrix objects for Pure Data
========================================
Homepage: https://git.iem.at/pd/iemmatrix
`iemmatrix` is a collection of objects for Pure Data (Pd)
that allow manipulation of simple matrices.
## Found a bug? Miss a feature?
Please use our issue-tracker at
https://git.iem.at/pd/iemmatrix/-/issues
## Installation instructions
### Simple installation
`iemmatrix` is available via deken (Pd's built in package manager):
For Pd>=0.56
- Open the `Tools` menu
- Select `Find externals...`
- Type **`iemmatrix`** and hit `Search`
- Select the first entry and click on `Install`
For older Pd versions, `Find externals...` can be found in the `Help` menu.
### Compiling iemmatrix
If deken does not offer any downloads for your system
(e.g. because you are stuck on an old OSX system with a PowerPC processor,
or you want to use a not-yet released version),
you can locally compile `iemmatrix` instead.
#### Dependencies
in order to compile iemmatrix, you will need some libraries/applications installed.
Some of these dependencies are optional.
If they are present during compilation, iemmatrix will have certain functionality
enabled, which might be missing otherwise.
- Pure Data
https://puredata.info/downloads
make sure you also have the development files (headers)
- GNU scientific library (aka gsl) [optional]
https://www.gnu.org/software/gsl/
needed for higher maths, including eigenvalues and singular-value decomposition
- FFTW (Fast Fourier Transform) [optional]
https://fftw.org
fast, high-precision FFTs; if not present, iemmatrix will use Pd's internal FFT
- sndfile (reading/writing audio files) [optional]
https://libsndfile.github.io/libsndfile/
for reading soundfiles into matrices (many soundfiles are supported)
- the `pkg-config` tool (to detect) the optional dependencies
- a compiler, linker,...
tested with
- GCC (the GNU compiler collection)
- Clang
#### Building
iemmatrix uses the [pd-lib-builder](https://github.com/pure-data/pd-lib-builder) build system.
just run:
```sh
make
```
To get some basic help with the build-system run
```sh
make help
```
or read the [online documentation for pd-lib-builder](https://github.com/pure-data/pd-lib-builder).
#### Installing
The ordinary way to install, is by running the following with the proper privileges
(e.g. as root):
```sh
make install
```
This will install the entire iemmatrix into `/usr/local/lib/pd-externals/iemmatrix/`
On systems that have no standard filesystem layout for Pd-externals (e.g. W32 and macOS),
this is not exactly what you want.
Instead, you can use the following to collect all installation data into a single directory:
```sh
make install DESTDIR=$(pwd) pkglibdir=
```
This will create a new directory `iemmatrix` (in your current directory),
containing all binaries and abstractions needed.
You can then take this directory, and put it into a place, where Pd will look for it:
E.g.
| OS | path | example path
|---------|----------------------------|------------------------------------------------------
| Linux |`~/.local/lib/pd/extra` | `/home/frodo/.local/lib/pd/extra/iemmatrix`
| macOS | `~/Documents/Pd/externals` | `/Users/frodo/Documents/Pd/externals/iemmatrix`
| Windows | `%AppData%\Pd` | `C:\Users\frodo\AppData\Roaming\Pd\iemmatrix`
A full list of default search paths for externals, can be found at
https://puredata.info/docs/faq/how-do-i-install-externals-and-help-files/
## System-specific instructions
### Linux (Debian-based)
`iemmatrix` is available as a Debian package
```sh
apt-get install pd-iemmatrix
```
To get all the build-dependencies, use:
```sh
apt-get build-dep pd-iemmatrix
```
or manually with:
```sh
apt-get install build-essential puredata libfftw3-dev libsndfile1-dev libgsl0-dev
```
### macOS
The additional dependencies are available via [`brew`](https://brew.sh)
```
brew install pkgconf gsl fftw libsndfile
```
Then proceed with the [building instructions](#building)
### Windows
You will need the [MSYS2](https://www.msys2.org/) environment with [MinGW](https://www.mingw-w64.org/) installed.
Open an MinGW shell (`MSYS2 MinGW 64-bit`; for older 32bit Windows systems use `MSYS Mingw 32-bit`)
and install the dependencies with:
```sh
pacman -Suy \
${MINGW_PACKAGE_PREFIX}-gcc \
${MINGW_PACKAGE_PREFIX}-pkgconf \
${MINGW_PACKAGE_PREFIX}-ntldd \
${MINGW_PACKAGE_PREFIX}-libsndfile \
${MINGW_PACKAGE_PREFIX}-fftw \
${MINGW_PACKAGE_PREFIX}-gsl
```
Then proceed with the [building instructions](#building)
