vertcat

Concatenate fi object arrays vertically

collapse all in page

Syntax

C = vertcat(A,B)
C = vertcat(A1,A2,…An)

Description

C = vertcat(A,B) concatenates B vertically to the end of A when any of A and B is a fi object.

A and B must have the same number of columns. Multidimensional arrays are vertically concatenated along the first dimension. The remaining dimensions must match.

example

C = vertcat(A1,A2,…An) concatenates A1,A2,…An vertically when any of A1,A2,…An is a fi object.

A and B must have the same number of columns. Multidimensional arrays are vertically concatenated along the first dimension. The remaining dimensions must match.

vertcat is equivalent to using square brackets for vertically concatenating arrays. For example, [A; B] is equal to vertcat(A,B) when A and B are compatible arrays.

Horizontal and vertical concatenation can be combined, as in [a b;c d].

[a b; c] is allowed if the number of rows of a equals the number of rows of b, and if the number of columns of a plus the number of columns of b equals the number of columns of c.

The matrices in a concatenation expression can themselves be formed via a concatenation, as in [a b;[c d]].

Note

The fimath and numerictype objects of a concatenated matrix of fi objects C are taken from the leftmost fi object in the list A1,A2,…An.

Examples

collapse all

Create two matrices and concatenate them vertically, first by using square bracket notation, and then by using vertcat.

A = fi([1 2 3; 4 5 6])
A = 

     1     2     3
     4     5     6

          DataTypeMode: Fixed-point: binary point scaling
            Signedness: Signed
            WordLength: 16
        FractionLength: 12
B = fi([7 8 9],0,8)
B = 

     7     8     9

          DataTypeMode: Fixed-point: binary point scaling
            Signedness: Unsigned
            WordLength: 8
        FractionLength: 4
C = [A; B]
C = 

    1.0000    2.0000    3.0000
    4.0000    5.0000    6.0000
    7.0000    7.9998    7.9998

          DataTypeMode: Fixed-point: binary point scaling
            Signedness: Signed
            WordLength: 16
        FractionLength: 12
D = vertcat(A,B)
D = 

    1.0000    2.0000    3.0000
    4.0000    5.0000    6.0000
    7.0000    7.9998    7.9998

          DataTypeMode: Fixed-point: binary point scaling
            Signedness: Signed
            WordLength: 16
        FractionLength: 12

Note that the numerictype of concatenated matrix D is taken from the leftmost fi object in the input list.
