dovs {stokes}

Dimension of the underlying vector space

Description

A k-form \omega\in\Lambda^k(V) maps V^k to the reals, where V=\mathbb{R}^n. Function dovs() returns n, the dimensionality of the underlying vector space. The function itself is almost trivial, returning the maximum of the index matrix.

Special dispensation is given for zero-forms and zero tensors, which return zero.

Vignette dovs provides more discussion.
