Scilab Function

spaninter - subspace intersection

Calling Sequence

[X,dim]=spaninter(A,B [,tol])

Parameters

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).
