A set of m linear equations in n unknowns has the m*n matrix A of coefficients
and the m×l (column)vector h^T of right-hand sides.(Later We shall write this as Ax^T=h^T)
In each of cases (a) to (d) below,ansWer as many as possible of the following questions.
Can the situation occur?
If so,is the set of equations consistent?
If so,how many parameters has the solution?
a.m=9 n=r(A)=r(A:h^T)=4
b.m=n=7 r(A)=5 r(A:h^T)=6
c.m=5 n=7 r(A)=5 r(A:h^T)=3
d.m=3 n=4 r(A)=r(A:h^T)=5

a. 方程组有唯一解
b. 方程组无解
c. 无解
d. 这个不可能, 矩阵的秩不超过其行数与列数

我也看不懂
