How to evenly splice two block matrices together

Given the block matrices

[A1, A2, A3, ... AN] and [B1, B2, B3, ... BN]

I would like to form

[A1, B1, A2, B2, A3, B3, ... AN, BN]

Is there a quick and dirty way to do this?

[Torsten]

If the matrices are really named A1,A2,...,AN ; B1,B2,...,BN, there is no other way than writing one after the other. This should show you that this sort of numbering has severe disadvantages for handling.

In particular what I want to do is form

[A1, Z, A2, Z, A3, Z, ... AN, Z]

where Z is a zero matrix (that does not necessarily have the same number of columns as Ai). How about for this case? The question I originally posed is indeed a generalization of this.

Are you trying to form the block diagonal? blkdiag()

[Travis Arnold]

@Walter nope. Horizontal concatenation.

Answer 1

[Walter Roberson]

The quick way is not to use individual variables for those. Put them in cell row vectors. Then

Temp = [Acell; Bcell] ;
Result = [Temp{:}] ;

The interleave logic relies on Acell and Bcell being 1xN cell arrays.

This is the kind of solution I was looking for; I figured something with cell arrays would be the best solution. Thanks Walter!
