The following notation is from the book "Frames and Bases."
Let f and g be vectors in [tex]R^{n}[/tex] with the usual dot product <,>.
Then, what does the notation [tex]\left|\left\langle f,g\right\rangle\right|^{2}[/tex] mean?
Specifically, does it mean [tex]\left|\sum^{n}_{i=1}f_{i} g_{i}\right|[/tex]
or does it mean [tex]\left(\sum^{n}_{i=1}f_{i} g_{i}\right)^{2}[/tex]
