Hi,
Communicating with hardware over PCI Express (PCIe) in MATLAB typically involves interfacing with the hardware at a low level, which often requires specialized support for the protocol and hardware being used. The AXI Manager for PCI Express is a common way to facilitate this communication, especially for FPGA-based designs, because it simplifies the process of data transfer between the host (running MATLAB) and the FPGA device.
However, if for some reason you're looking to communicate with a PCIe device without using the AXI Manager for PCI Express, you might consider the following alternatives:
1. MATLAB's Support for C/C++ and MEX Files
You can write custom C/C++ code that interfaces directly with the PCIe device using the appropriate OS-specific system calls (e.g., using Windows' DeviceIoControl or Linux's ioctl). This code can then be compiled into a MEX file, which MATLAB can execute. This approach requires a good understanding of both the PCIe device's API (if available) and MATLAB's MEX file compilation process.

2. Instrument Control Toolbox
MATLAB's Instrument Control Toolbox provides functions for communicating with a wide range of instruments and devices. While it's more commonly used for devices connected via GPIB, Serial, TCP/IP, and similar interfaces, it can also be used to communicate with devices for which you can develop or use existing drivers. The toolbox allows MATLAB to send and receive data over these interfaces, and with the right driver or SDK for your PCIe device, you might be able to leverage this toolbox for your communication needs.

Hope it helps.
