using umatrix in OpenMV

I am trying to use the umatrix library in OpenMV but seems that it is not opening with I import umatrix at the beggining of the code.

https://github.com/openmv/openmv/blob/master/scripts/libraries/umatrix.py

I am not sure how to use it.

Kind regards, jl1982fm

What’s the error?

That when I was adding in import in the beginning of the code I was not able to see it in blue, but now that I copy it to the root folder of the SD card seems I can access it.
