An architect accepts a commission from a client. The commission might involve preparing feasibility reports, building audits, the design of a building or of several buildings, structures, and the spaces among them. The architect participates in developing the requirements the client wants in the building.
Dimension (vector space) In mathematics, the dimension of a vector space V is the cardinality (i.e. the number of vectors) of a basis of V over its base field. For every vector space there exists a basis, and all bases of a vector space have equal cardinality; as a result, the dimension of a vector space is uniquely defined.
Of course the orientation is important, else MATLAB could simply tell you the vector is of length n. In the latter case, there is a trailing singleton dimension, so implicitly there are infinitely many trailing singleton dimensions. So that column vector is really of size nx1x1x1..., and a row vector is of size 1xnx1x1... The same is true of a scalar.
