摘要
矩阵是高等代数的一个非常重要的组成部分,通过例题给出了矩阵在数学计算中的一些应用,包括算由几个向量所生成的子空间的维数,利用矩阵的秩来判定一个方程组是否有解,通过对二次型的矩阵进行合同变换,将二次型化成标准形。
Matrix is a very important part of higher algebra by some application examples are given in the matrix math calculations, including the number of dimensions considered by several vector subspace generated by the matrix to determine the rank of a system of equations is solvable, by contract quadratic form matrix transformation, the quadratic form into standard.
