Working with Vectors
Thre are two completely different ways to enter a vector in Mathematica.
The List Approach: This is the standard Mathematica method. It does not distinguish between column and row vectors. Thus, Transpose cannot be used on these vectors.
The Matrix Approach: Here, a vector is entered as a special case of a matrix. This deoes distingushe between column and row vectors, so Transpose can be used with these vectors, Entering the vector this way takes more effort, but it can be less confusing and more ‘natural’ than the List approach.
Mixing the two approaches is not recommended, as this may cause error and confusion.
