MATLAB: Combining 2 matrices every other row

Question

Hello,

I have two matrices for example A = [1; 2; 3; 4; 5] and B = [A; B; C; D; E]. I would like to combine them in such a way that I get C = [1; A; 2; B; 3; C; 4; D; 5; E].

Can you please help me with this task? Thank you so much ?

Hi,

try:

A = [-1; -3; -5; -7; -9]
B = [2; 4; 6; 8; 10]
result = reshape(([A B])',[],1)

gives:

A =
    -1
    -3
    -5
    -7
    -9
B =
     2
     4
     6
     8
    10
result =
    -1
     2
    -3
     4
    -5
     6
    -7
     8
    -9
    10

or with symbolic variables:

syms a b c d e
A = [1; 2; 3; 4; 5];
B = [a; b; c; d; e];
result = reshape(([A B].'),[],1)

results in:

A =
     1
     2
     3
     4
     5
 
B =
 
 a
 b
 c
 d
 e
 
 
result =
 
 1
 a
 2
 b
 3
 c
 4
 d
 5
 e

Best regards
