# AffineChartProj -- use an affine chart on the projective space

## Synopsis

• Usage:
AffineChartProj => l

## Description

This is an optional input for some methods, and it works quite similar to AffineChartGrass. The argument l can be an integer between 0 and $n$, corresponding to an affine chart $U$ on the projective space $\mathbb{P}^n$. This indicates to the method that should perform internal computations using the chart $U$.
