1. 确定Mathematica代码中函数的输入、输出类型 被FunctionCompile的函数,输入能用"PackedArray"就不用"ListVector",运行效率会提高很多。 2. 确定C++代码中函数的输入、输出类型 在FunctionCompile中对PackedArray和CArray进行类型转换,不仅麻烦,编译速度慢,运行效率也低。 所以C++代码的输入、输出类型应为MTensor(即Fu...

In[1]:= Out[1]= In fact, this is the actual form used to send a vector to R, even when it is initially expressed in more succinct notation ({1,2,3} here). Add more attributes (properties) to your vector: In[2]:= Out[2]= The result is expressed in Mathematica: In[3]...
In this tutorial type paper a Mathematica function for Support Vector Regression has been developed. Summarizing the main definitions and theorems of SVR, the detailed implementation steps of this function are presented and its application is illustrated

By default, Mathematica considers vectors to be row vectors. The Flatten command can be used to convert a column vector into a row vector. ■ Conversion of a column vector to a row vector columnvector = {{1}, {2}, {3}} {{1}, {2}, {3}} Flatten[columnvector] {1, 2, 3} Mani...
