Hi there, if I have a matrix A of MxM and another matrix B column of Mx1. And a variable p.
When I say p = 1, I want to display a matrix C formed from the first line of the matrix A, to which I also add the first line from B.
Ex:
A = [ 1 2 3 4;
5 6 7 8;
9 10 11 12;
13 14 15 16 ]
B = [ 0;
1;
1;
0 ]
p = 1 --> C = [1 2 3 4 0]
p = 2 --> C = [1 2 3 4 0; 5 6 7 8 1]
p = 3 --> C = [1 2 3 4 0; 5 6 7 8 1; 9 10 11 12 1]
A little help, please

This should do it:
>> p=1;
>> [A(1:p,:),B(1:p,:)]
ans =
1 2 3 4 0
>> p=2;
>> [A(1:p,:),B(1:p,:)]
ans =
1 2 3 4 0
5 6 7 8 1
>>
