MatrixEntry

type MatrixEntry = number | boolean | SymbolicNode;

Defined in: packages/engine/src/vm/Value.ts:15

A single matrix cell. boolean covers element-wise comparison results ([1,6;3,8] < [5,2;7,4] produces a Matrix of booleans, not numbers). A SymbolicNode cell is a free-variable algebraic entry, e.g. s = [sx,0,0;0,sy,0;0,0,1] where sx/sy are never assigned, so those cells store a real SymbolicNode (a bare var node initially) rather than degrading to 0. See MatrixOps.ts’s entryToSymbolic()/ symbolicToEntry() for the two-way conversion every symbolic-aware matrix op (multiply, inverse, determinant) uses.
