To achieve this with MATLAB, you would need both ROS Toolbox license and Computer Vision Toolbox license. You can check whether you have these with:

If you have both licenses, you can follow these steps and examples to read from .bag format, convert to point cloud, and save to .pcd format:
- Read .bag files with rosbagreader, this example shows how to read specific message from the .bag file. You would need to select the topic that correspond to the sensor_msgs/PointCloud2 message in .bag file.
- Use rosReadXYZ (and rosReadRGB if you also want the color of the point cloud) from each of those ROS messages.
