v
]
finds the projection of the vector
u
onto the vector
v
.
Projection
[
u
,
v
,
f
]
finds projections with respect to the inner product function
f
.
MORE INFORMATION
For ordinary vectors
u
and

]
,
u
and
v
can be any expressions or lists of expressions for which the inner product function
f
applied to pairs yields real results.
