# Notes of Acoustic Toolbox
## Preperation
1. Check your interpreter (eg. gfortran)
```
$ gfortran --version
GNU Fortran (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0
Copyright (C) 2021 Free Software Foundation, Inc.

2. Check your system (eg. Ubuntu)
```
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 22.04.3 LTS
Release: 22.04
Codename: jammy
```
3. Download here: http://oalib.hlsresearch.com/AcousticsToolbox/

4. Extract (test_at)

## Makefile and test
1. Since the Makefile defaults to choosing gfortran, we simply need to execute it.
```
$ make
...
...
***********************************
***** Acoustics Toolbox built *****
***********************************
```
If you see the same output, it signifies the successful generation of executable files.
2. To make things clear, I will make a new folder test_at/at_mytest, and put all necessary files in it.

3. Now it's time to do the test. Open a terminal and type
```
$ ./bellhop.exe MunkB_Coh
```
4. Two files are generated, a prt file and an shd file. They are the output files for the test problem.

5. Open MATLAB and go to the same path to plot the results.
