Other Steps to Reproduce

ESP32 V1.0.6 compiles and function sucessfully.

I have checked existing issues, online documentation and the Troubleshooting Guide

esp-dl has changed since 1.0.6, and many parts were simply scrapped as they were too slow on the esp32. You can try to include dl_math_matrix.hpp, but it is very possible the function you are looking for is simply gone.

It is gone! See the changed examples included in the core 2.0.6 release.

This have been changed, closing as won't fix.

I have code for a esp32-cam car. What was "dl_lib_matrix3d.h" used for and how can I replace it so it works on 2.0.11? Thanks for any help.

it was used for face detection and face recognition. Now API is slightly different. You ca read more here
