最近在用matlab调用相机,相机有二次开发包里面有封装好的c语言编写的dll文件,但是里面的函数需要指向相机信息结构体的指针作为输入,我感觉并不是传递参数,而是传递一个地址,这个matlab可以实现吗,希望大家赐教

我将用英语回答您的询问
You can pass the pointer to camera information structure as an input to the function as shown in the code below:
% Create a pointer to the camera information structure
cameraInfoPtr = libpointer('your_structure_type', yourCameraInfo);
% Call the DLL function with the pointer
calllib('your_dll_file.dll', 'your_dll_function', cameraInfoPtr);
where,
Also, ensure that the DLL file is located in the MATLAB search path or specify the full file path if it is located elsewhere.
You may refer to the documentation here: Pointer object for use with shared C library - MATLAB libpointer - MathWorks India
