Lesson 12: Making Block Matrices in LATEX
按列分块:
[AAb⋯An−1b] $$ left[ egin{array}{c|c|c|c} A & Ab & cdots & A^{n-1}b end{array} ight] $$
左右分块:
⎡⎣⎢⎢⎢⎢⎢a11a21⋮an1a12a22an2⋯⋯⋱⋯a1na2n⋮annb1b2⋮bn⎤⎦⎥⎥⎥⎥⎥ $$ left[ egin{array}{cccc|c} a_{11}&a_{12}&cdots&a_{1n}&b_1\ a_{21}&a_{22}&cdots&a_{2n}&b_2\ vdots&&ddots&vdots&vdots\ a_{n1}&a_{n2}&cdots&a_{nn}&b_n\ end{array} ight] $$
四个对角:
C=[ACBD] $$ C= left[ egin{array}{c|c} A& B \ hline C& D end{array} ight] $$
