vertcat (MATLAB Functions)

Concatenate arrays vertically

Syntax

```
C = vertcat(A1, A2, ...)
```

Description

C = vertcat(A1, A2, ...) vertically concatenates matrices A1, A2, and so on. All matrices in the argument list must have the same number of columns.

vertcat concatenates N-dimensional arrays along the first dimension. The remaining dimensions must match.

MATLAB calls C = vertcat(A1, A2, ...) for the syntax C = [A1; A2; ...] when any of A1, A2, etc. is an object.

Examples

Create a 5-by-3 matrix, A, and a 3-by-3 matrix, B. Then vertically concatenate A and B.

A = magic(5);            % Create 5-by-3 matrix, A
A(:, 4:5) = []

A =

    17    24     1
    23     5     7
     4     6    13
    10    12    19
    11    18    25


B = magic(3)*100         % Create 3-by-3 matrix, B

B =

   800   100   600
   300   500   700
   400   900   200


C = vertcat(A,B)         % Vertically concatenate A and B

C =

    17    24     1
    23     5     7
     4     6    13
    10    12    19
    11    18    25
   800   100   600
   300   500   700
   400   900   200
