本Matlab程序对需要高速穿越大气层的返回舱进行了纵向三自由度的模拟计算，只需输入如下基本参数，初始速度，再入高度，再入角。程序中有比较详细的说明。大气模型采用了真实的1976年美国标准大气模型，内附计算标准大气模型的Matlab程序，只需输入高度和高度间隔即可求出详细的参数值。(The Matlab program calculates the longitudinal three degrees of freedom of a reentry module that requires high speed passage through the atmosphere. Only basic parameters such as initial velocity, reentry height and reentry angle are entered. There are more detailed instructions in the program. The atmospheric model uses the real 1976 American Standard atmosphere model, which contains the Matlab program for calculating the standard atmospheric model. Only the input height and height interval can be used to find the detailed parameter values.)
