简单认为是编译器,它可以编译很多种编程语言(括C、C++、Objective-C、Fortran、Java等等)。当你的程序只有一个源文件时,直接就可以用gcc命令编译它。但当你的程序包含很多个源文件时,用gcc命令逐个去编译时,你就很容易混乱而且工作量大,所以出现了make工具。 2.什么是make make工具可以看成是一个智能的批处理工具...

In MATLAB, when you access a slice of an array and assign it to a variable, MATLAB will make a copy of that portion of the array into your new variable. This means that when you assign values to the slice, the original array is not affected. Try out this example to help explain the...
