How to merge different matrices?

Hello

I have three different matrices:

S1 = [10x10.000 double]; S2 = [10x9.480 double]; S3 = [7x8.770 double];

And now, I would like to put all them together in one matrix or vektor.

Does anybody have an idea how can I realize that?

Putting them into one vector is easy:

vec = [S1(:);S2(:);S3(:)];

If you need more complicated "merging" than this, then you need to tell us, e.g. leading padding, trailing padding, value to pad with, dimension to concatenate along, etc, etc.
