about observation and action vectors

[yyang8891]

Hi all, I find the env simply outputs a vec of state observation and accepts action vec of actuators (mostly a subset of all voxels), while both of them (corner points and all voxels) are arrange in matrix format by default. So may I ask if anyone could please make it clear how are the two matrices converted into vectors? How do the 2-D coordinates correspond to vector indexes? Are they simply aligned from the top-left corner to down-right element like most of the cases in image processing treatments? I'll be very gratefull if anyone give me a hint, thanks in advance!

Hi, you can refer to this page for more details about the observarion (https://github.com/Yuxing-Wang-THU/ModularEvoGym)
