RadISpeC program code (.m files and GUI for Matlab IDE)

Radiation: Interface for Matlab Spectroscopy Calculations (RadISpeC) is a program that use HITRAN/HITEMP data to generate Line-by-Line (LBL) spectra at a wanted spectral resolution and environment. These data can be used with Discrete Transfer Methods (DTM), Ray Tracing (RT) etc. solvers to estimate high precision radiation in heated flow problems. It was created as a part of the article "Experimental and theoretical evaluation of spectral radiative transfer in high-pressure flames" by Westly et. al. from 2019 (under review by Journal atm). This article also show how well the program is at simulating heated gas flows for CO2, H2O and CO compared to experimental results. The program contain all setups that was used for the article to use free of charge, as long as the program and article is cited. All functions have descriptions that explain how to use them and contain call methods. If a more detailed description of theory is wanted, check the RadISpeC documentation PDF inside the RadISpeC folder. This PDF also contain the same information as the function descriptions. The program work fully with the Matlab IDE for 2017b. If the user want to use the created GUI, the Matlab version has to be 2017b or newer. This lies in the function UIFigure that is used, which after an update from 2017a to 2017b made it uncompatible with older Matlab versions. It is possible to request an ".exe" with a standalone version of the program that use the GUI by contacting Anders Ivarsson from DTU MEK <br>辐射光谱计算Matlab交互界面（RadISpeC）是一款依托HITRAN/HITEMP数据库，可在指定光谱分辨率与环境参数下生成逐线（Line-by-Line, LBL）光谱的程序。该类数据可配合离散传递法（Discrete Transfer Methods, DTM）、光线追踪（Ray Tracing, RT）等求解器，用于估算热流问题中的高精度辐射场。本程序衍生自Westly等人2019年发表的论文《高压火焰光谱辐射传递的实验与理论评估》（目前正由《Journal atm》期刊审稿）。该论文同时验证了本程序针对二氧化碳（CO₂）、水蒸气（H₂O）及一氧化碳（CO）的热气流模拟效果与实验结果的吻合程度。程序附带了该论文中使用的全部配置参数，可免费使用，但需在使用时引用本程序及原研究论文。所有函数均配有详细使用说明与调用方法示例。若需获取更详细的理论背景描述，可查阅RadISpeC文件夹内的RadISpeC文档PDF，该PDF同样包含函数使用相关的全部说明信息。本程序可完全兼容2017b及以上版本的Matlab集成开发环境（Integrated Development Environment, IDE）。若需使用内置图形用户界面（Graphical User Interface, GUI），则Matlab版本需为2017b或更新版本，这是因为程序所使用的UIFigure函数仅在Matlab从2017a升级至2017b后得到支持，旧版本Matlab无法兼容该函数。用户可通过联系丹麦技术大学机械工程系（DTU MEK）的Anders Ivarsson，申请带GUI的独立可执行文件（.exe）版本。
