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界面工具（RadISpeC）是一款依托HITRAN/HITEMP数据库的程序，可基于指定光谱分辨率与环境参数生成逐线（Line-by-Line, LBL）光谱。所得光谱可配合离散传递法（Discrete Transfer Methods, DTM）、光线追踪（Ray Tracing, RT）等求解器，用于估算加热流动问题中的高精度辐射场。本程序由Westly等人于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》审稿）衍生而来。该论文同时验证了本程序在模拟二氧化碳（CO₂）、水（H₂O）与一氧化碳（CO）加热气体流动时的仿真精度，其结果与实验数据吻合良好。本程序包含论文中所用的全部配置项，可免费使用，但需在使用时引用本程序与该论文。所有函数均附带使用说明与调用方法详解。若需获取更详细的理论说明，请查阅RadISpeC文件夹内的RadISpeC文档PDF文件，该PDF同样涵盖函数说明中的全部内容。本程序可完美适配Matlab 2017b版本的集成开发环境（IDE）；若需使用内置图形用户界面（GUI），则Matlab版本需为2017b及更新版本，这是因为程序调用的UIFigure函数在Matlab 2017a至2017b的更新中进行了调整，导致旧版本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，获取带图形用户界面的独立运行版.exe程序。
