ネスト化されたcellをアンネストする

More than 5 years have passed since last update.

c={{1,2,3},{4,5,6,7}}

といったようにネスト化されたcellを,

d={1,2,3,4,5,6,7}

とアンネストすることを考える.この場合,

>> d=[c{:}]
d = 
    [1]    [2]    [3]    [4]    [5]    [6]    [7]

として簡単に書けることが知られている.ところが,

c_vert={{1;2;3};{4;5;6;7}}

と垂直方向にセルが並んでいる場合,

>> d_vert=[c_vert{:}]
Error using horzcat
CAT arguments dimensions are not consistent.

とエラーを吐かれてしまいうまくいかない.これは,[]を使った結合では水平方向の結合(horzcat)がデフォルトで呼ばれてしまうためである.
このような場合,vertcatコマンドを使う.

>> d_vert=vertcat(c_vert{:})
d_vert = 
    [1]
    [2]
    [3]
    [4]
    [5]
    [6]
    [7]
