vcat

vcat(A...)

Concatenate along dimension 1

Examples

julia> foo = Array(Int8,2,2)
2x2 Array{Int8,2}:
 2  0
 0  0
julia> bar = Array(Int8,2,2)
2x2 Array{Int8,2}:
 -93    -111
 62             5
julia> vcat(foo,bar)        # equivalent to [foo; bar]
4x2 Array{Int8,2}:
 2      0       
 0      0
 -93     -111
 62      5

# Concatenate arrays vertically along dimension 1
julia> A = [1 2 3; 4 5 6]
2×3 Array{Int64,2}:
 1  2  3
 4  5  6

julia> B = [7 8 9]
1×3 Array{Int64,2}:
 7  8  9

julia> C = [10 11 12; 13 14 15]
2×3 Array{Int64,2}:
 10  11  12
 13  14  15

julia> D = vcat(A, B, C)
5×3 Array{Int64,2}:
  1   2   3
  4   5   6
  7   8   9
 10  11  12
 13  14  15

In this example, vcat is used to vertically concatenate arrays A, B, and C along dimension 1, resulting in a new array D. The resulting array D has 5 rows and 3 columns.

Note that vcat can be used with any number of arrays, separated by commas. This allows for concatenation of multiple arrays in a single function call.
