中文说明：通过定义初始矩阵，该矩阵为四阶矩阵，然后，利用matlab源程序将其变量进行更换，然后将更换后的变量带入原初始矩阵中，再使得矩阵进行连乘，最后，利用程序进行相乘之后的矩阵元素的提取，进而达到矩阵元素的传递与变换。
English Description：
Through the definition of the initial matrix, the matrix is a fourth-order matrix, and then, the matlab source program is used to replace its variables, and then the replaced variables are brought into the original initial matrix, and then the matrix is multiplied. Finally, the program is used to extract the matrix elements after multiplication, so as to achieve the transfer and transformation of matrix elements.
