Let's hope I'm calling it well, I have this vector, or matrix, now I really don't know what it is
{
{{1,0.4,0,0,0,0},{2,0.5,0,0,0,0},{3,0.2,0,0,0,0}},
{{3,0.2,1,5.5686,23.618,1},{2,0.5,0,0,0,0},{1,0.4,0,0,0,0}}
{{2,0.2,0,5.5686,23.618,1},{3,0.5,0,0,0,0},{1,0.4,0,0,0,0}}
}
I want to sort the second level vectors, in a particular manner that the smallest vectors are ordered by their first element, so they all follow the 1,2,3 order in the first element:
{
{{1,0.4,0,0,0,0},{2,0.5,0,0,0,0},{3,0.2,0,0,0,0}},
{{1,0.4,0,0,0,0},{2,0.5,0,0,0,0},{3,0.2,1,5.5686,23.618,1}}
{{1,0.4,0,0,0,0},{2,0.2,0,5.5686,23.618,1},{3,0.5,0,0,0,0}}
}
I was trying different ways, the last one being the following that I found in another question, but it only sorts a common matrix of the type:
{ { }, { } }
But not of the type:
{ { { } , { } } , { { } , { } } }
This is the code:
For[i = 1, i <= Length[BigVector], i++,
SortBy[BigVector[[i]], #[[1]] &]];
