2011年考研数学线性代数特点及复习建议（Characteristics and review of mathematical linear algebra for postgraduate entrance examination in 2011） 2011 national graduate admission test was conducted on January 15-16, are over now. All the students after a year of hard work, hard work, finally finished all courses. For the math exam candidates, more hope to understand the general characteristics of this math exam; and for many students ready to participate in the examination in 2012 also hope to understand the trend of mathematical proposition for next year, according to the following linear algebraic part of item analysis. Linear algebra is a total of 5 questions, two multiple-choice questions, a fill in the blanks, two questions, two questions, 22 points this year, these two big questions are math, and math one or two, reference is exactly the same, a linear vector table is out of the question, a a closed real symmetric matrix problem. Compared with the linear algebra topics for 10 years, this years title of linear algebra with 10 years of difficulty, two big problems in 10 years, the number one, number two, the first big problem are investigated by solving a nonhomogeneous linear equations with parameters, this problem relates to the parameter the problems and solutions of nonhomogeneous linear equations of the structure, and this years first big issue on two may between the vector group linear table is out of the question, as a matter of fact it is non homogeneous linear equations, but the first question relative to the 10 years, slightly stronger flexibility. You can not according to the first table, namely equations has no solution parameters, then the second question: will use linear representation, in essence is still required for solving equations, equations matrix coefficients are three, we only need to coefficient matrix and constant all together to elementary transformation that is, the elementary row transformation. For the second big questions, number one, number two, three
