I have tried with blockarray like



begin{align*}
B=
left[begin{blockarray}{ccccc}
a_{s_0} & a_{s_0+1} & cdots &cdots &a_{s_0+n}\
%begin{blockarray}{cccccc}
%begin{block}{ccccc|c}
begin{block}{cccc|c}
cline{1-4}
a_{s_0+1} & a_{s_0+2}&cdots &cdots &a_{s_0+n+1}\
vdots & vdots & & & \
0 & 0 &cdots & 0 & b \
vdots & vdots & & & \
a_{s_0+n} &a_{s_0+n+1} &cdots &cdots & a_{s_0+2n}\
%end{block}
%end{blockarray}
end{block}
end{blockarray}right]
end{align*}


but I'm not able to handle the vertical line.

          You don't really need blkarray for that: an ordinary array will do:



          documentclass{article}

          usepackage{mathtools}

          begin{document}

          begin{align*}
          B=
          left[begin{array}{c|ccc|c}
          a_{s_0} & a_{s_0+1} & cdots & multicolumn{1}{c}{cdots} &a_{s_0+n}\
          cline{1-4}
          a_{s_0+1} & a_{s_0+2}&cdots &cdots &a_{s_0+n+1}\
          vdots & vdots & & & vdots \
          0 & 0 &cdots & 0 & b \
          vdots & vdots & & & vdots \
          cline{2-5}
          multicolumn{1}{c}{a_{s_0+n}} &a_{s_0+n+1} &cdots &cdots & a_{s_0+2n}\
