How to calculate distance of objects from depth data in MATLAB?

Hi~, I am using matlab and D415, and have gotten the depth data by following the matlab example. However, I didn't find the example for calculating distance of objects from the depth data.

I found that in a python example librealsense/distance_to_object.ipynb at jupyter · IntelRealSense/librealsense · GitHub, there is a way to calculate distance:

depth = np.asanyarray(aligned_depth_frame.get_data()) 
# Crop depth data: 
depth = depth[xmin_depth:xmax_depth,ymin_depth:ymax_depth].astype(float) 
# Get data scale from the device and convert to meters 
depth_scale = profile.get_device().first_depth_sensor().get_depth_scale() 
depth = depth * depth_scale# depth is the distance of the object

Obviously, the code above for python does not work in matlab.

So, how to calculate distance of objects in matlab?

Many thanks.
