我有一个问题,如何逐个读取矩阵行?
我已经使用命令:
rows = Table[assembly[[a]], {a, 16}]
Table[Position[rows, bar][[All, 2]], {bar, 150}]
MatrixForm[Position[rows, 49]]
baris = Flatten[Position[rows, 49], 1]
Table[Position[rows, kol][[All, 2]], {kol, 150}]
MatrixForm[Position[rows, 50]]
kolom = Flatten[Position[rows, 50], 1]
{Table[Position[rows, bar][[All, 2]], {bar, 150}],
Table[Position[rows, kol][[All, 2]], {kol, 150}]}
最后,我不能简单地从我的矩阵16x24创建矩阵150x150。 如何在mathematica中实现?
谢谢你
PS:这是装配矩阵:
