📜 Flattening Visualizer
Watch each number slide — slowly, one at a time — from its 3D spot into a flat chain.
📋 How To Use This Lab
Look at the two grids up top — that's your 3D tensor:
2 separate channels
, each a 3×3 grid.
Pick
Start Dim
and
End Dim
below
→
those axes will merge into one.
Press the big
▶ Play Unfold
button
→
watch every number slide, one at a time, into its new flat position.
Try
Start Dim = End Dim
→
nothing moves at all — that's a real no-op.

🧑🏫 PROF. TORCH
Flatten never reorders memory — it's just a view that merges dimensions, so the data order stays identical.
