i have two matrices A & B. The no. of rows in A are 4 and elements 5. The no. of rows in B are 3 and elements 5.

I want to create matrix C such that its first row is first row of A. Then C second row should be 1st row of B.

E.g A= [ 1 3 4 5 7 ;4 5 6 6 7;5 3 2 1 2; 2 2 2 3 4 ]

B=[1 1 1 2 3 ;1 2 4 6 7 ;3 5 6 7 8 ]

Then C should be C=[1 3 4 5 7 ;1 1 1 2 3;4 5 6 6 7;1 2 4 6 7 ;5 3 2 1 2 ;3 5 6 7 8 ;2 2 2 3 4]

It is requested to provide me the code so that i can generate matrix C as mentioned above (i.e. alternate rows of A & B)

Try something like:

A = [1 3 4 5 7; 4 5 6 6 7; 5 3 2 1 2; 2 2 2 3 4];
B = [1 1 1 2 3 ; 1 2 4 6 7; 3 5 6 7 8];
C = zeros(size(A,1)+size(B,1),size(A,2));
C(1:2:end,:) = A;
C(2:2:end,:) = B;
C = 7×5
     1     3     4     5     7
     1     1     1     2     3
     4     5     6     6     7
     1     2     4     6     7
     5     3     2     1     2
     3     5     6     7     8
     2     2     2     3     4
