This is the Matlab fluid mechanics calculation software designed to compute standard parameters in fluid dynamics. The software is developed using Qt and is compatible with Matlab for calculations. The tool is available as 'V1.0.1 boxed.zip' for direct use through the '标准大气参数计算软件.exe' executable. Additionally, you can perform calculations manually using the 'calculate.m' script in Matlab. The software relies on standard equations for fluid mechanics parameter calculations. The program was created in Qt Creator 4.11.0 and supports Qt 5.14.1 (MinGW 64-bit).
