Mathematica(@mathemetica):Scalars carry zero indices as lone values a. Vectors gain one as vᵢ packing n components into a column. Matrices take two as Mᵢⱼ filling m×n grids. 3-tensors use three as Aᵢⱼₖ arranging m×n×p entries in cubes. 4-tensors add four as Bᵢⱼₖₗ holding m×n×p×q values in hypercubes. Structural engineers feed the elasticity 4-tensor into finite-element codes that predict how steel beams twist and yield under seismic shear in high-rise frames.
