矩阵体积是行列式的绝对值对矩形矩阵的推广。特别地,矩阵体积可以在变量变换公式中使用,而不是行列式(如果基础变换的雅可比矩阵是矩形的)。这一结果适用于曲面上的积分,这里通过几个例子说明。
The matrix volume is a generalization, to rectangular matrices, of the absolute value of the determinant. In particular, the matrix volume can be used in change-of-variables formulae, instead of the determinant (if the Jacobi matrix of the underlying transformation is rectangular). This result is applicable to integration on surfaces, illustrated here by several examples.
