spaninter
subspace intersection
Calling Sequence
[X,dim]=spaninter(A,B [,tol])
Arguments
- A, B
two real or complex matrices with equal number of rows
- X
orthogonal or unitary square matrix
- dim
integer, dimension of subspace range(
A
) inter range(B
)
Description
computes the intersection of range(A
) and range(B
).
The first dim
columns of X
span this intersection i.e.
X(:,1:dim)
is an orthogonal basis for
range(A
) inter range(B
)
In the X
basis A
and B
are respectively represented by:
X'*A
and X'*B
.
tol
is a threshold (sqrt(%eps)
is the default value).
