# Equivalence theorem for nonsingular matrices: the rows of A are a basis for R^n (or C^n).

Put content here**Theorem:** An  	imes n$ matrix $ is nonsingular if and only if The rows of $A$ form a basis for $\mathbb{R}^n$ (or $\mathbb{C}^n$). Being a basis means the rows are both linearly independent and spanning, which characterizes a nonsingular matrix.
