本例通过VC实现二维快速傅里叶变换，涉及到进行矩阵、复数等数学运算，运用了C语言动态内存分配、文件操作、结构指针的函数调用等内容。-In this case through the VC to achieve two-dimensional fast Fourier transform, related to the matrix, such as complex mathematics, use the C language, dynamic memory allocation, file operations, structure, function pointer to call and so on.
