Value
Description
This function calculates the distance between the two subspaces with equal dimensions span(A) and span(B), where A \in R^{p\times u} and B \in R^{p\times u} are the basis matrices of two subspaces. The distance is defined as
\|P_{A} - P_{B}\|_F/√{2d},
where P is the projection matrix onto the given subspace with the standard inner product, and d is the common dimension.
Usage
1
subspace(A, B)
Arguments
A
A p-by-u full column rank matrix.
B
A p-by-u full column rank matrix.
Value
Returns a distance metric that is between 0 and 1
