# Vismatrix – Visualization of sparse matrices
Vismatrix is a nice tool to visualize sparse matrices in (.smat) format
## Installation (Ubuntu/Linux)
```bash
sudo apt install libgl1-mesa-dev libglut-dev
bash all.bash
```
## Acknowledgements
To [Professor David Gleich](https://github.com/dgleich) for this wonderful tool.

## Installation
**1** Install dependencies (tested on **Ubuntu 23.04 LTS**):
```
sudo apt-get install freeglut3-dev libxmu-dev libxi-dev libz-dev g++ make cmake
```
**2** Download the code into /tmp/vismatrix:
```
git clone --depth 1 https://github.com/cpmech/vismatrix.git /tmp/vismatrix
```
**3** Compile the code (in /tmp/build-vismatrix):
```
./all.bash
```
**4** The executable file will be /tmp/build-vismatrix and you may install into /usr/local/bin by using:
```
sudo cp /tmp/build-vismatrix/vismatrix /usr/local/bin/
```
## Usage
The matrix input file is quite simple (0-index based):
```
m n nnz
i j x
...
i j x
```
where the first line has _m_ as the number of rows, _n_ as the number of columns, and _nnz_ as the number of non-zero values. The following lines contain the index of row _i_ and column _j_ of the non-zero entry _x_.
See [example.smat](https://github.com/cpmech/vismatrix/blob/master/example.smat) file.
Usage:
```
vismatrix example.smat
```
Some commands:
* right-click to Exit
