3.1 Vectors in 2-Space, 3-Space, and n-Space

Equivalent vector representations

Span of two non-parallel space vectors

Computing a linear combination of vectors in MATLAB using row matrix form:

>> v=[2 7 -1] v = 2 7 -1 >> w=[1 -2 0] w = 1 -2 0 >> 3*v+4*w ans = 10 13 -3

Now using column matrix form:

>> v=[2;7;-1] v = 2 7 -1 >> w=[1;-2;0] w = 1 -2 0 >> 3*v+4*w ans = 10 13 -3
