cat
2cat
Purpose Concatenate arrays
Syntax C = cat(dim,A,B)
C = cat(dim,A1,A2,A3,A4...)
Description C = cat(dim,A,B) concatenates the arrays A and B along dim.
2-212
C = cat(dim,A1,A2,A3,A4,...) concatenates all the input arrays (A1, A2, A3,
A4, and so on) along dim.
cat(2,A,B) is the same as [A,B] and cat(1,A,B) is the same as [A;B].
Remarks When used with comma separated list syntax, cat(dim,C{:}) or
cat(dim,C.field) is a convenient way to concatenate a cell or structure array
containing numeric matrices into a single matrix.
Examples Given,
A = B =
1 2 5 6
3 4 7 8
concatenating along different dimensions produces:

C = cat(1,A,B) C = cat(2,A,B) C = cat(3,A,B)
A = magic(3); B = pascal(3);
C = cat(4,A,B);
