We've studied that the wide-sense elementary transformation of a matrix, and illustrated its application in determinantcalculation, matrix inversion and the rank of a matrix.
We will give a general model of solving problems with construction and study its applications in the theory of determinant, in proof problems and calculation problems.
对构造法解题的一般模式及其在行列式的理论、证明题和计算题中的应用进行了探讨。

A novel tri-al function has been employed in the calculation, its determinant being composed of the localized molecular orbitals on the basis of the hydrogen-like functions.
