二次型的判定及相关问题的计算机实现

On determining definite properties for real quadratic form and realizing by computer

以 Mathematica系统为工具 ,讨论一般二次型的判定及相关问题以及带约束条件的二次型的判定问题 .

To present a Mathemiatica program,which can swiftly detemine the definite properties for real quadratic form,by the way,to determine the definite properties for real quadratic form under linear constrains.
