Insert two elements in a multidimensional array

Asked by Cesar Ramirez on 18 Feb 2019
Latest activity Commented on by Cesar Ramirez on 18 Feb 2019
Hi, I want to insert two elements (h1,h2) into my multi array called xh after its initialized all with zeros.
N = 50;
xh = zeros(2,N);
[h1,h2] = cruza(x(:,p1),x(:,p2));
%Insert h1 and h2 into xh
The function "cruza" returns elements to insert into xh
function [xh1,xh2] = cruza(xp1,xp2)
D=2;
pc = randi([1 D]);
xh1 = [xp1(1:pc) ; xp2(pc+1:D)];
xh2 = [xp2(1:pc); xp1(pc+1:D)];

Let's suppose that N = 5 instead of 50. Then
xh = [0 0 0 0 0;
0 0 0 0 0]
What size are h1 and h2? (Please give an example of what they look like.) Where do you want to insert them into xh? How do we know that?
Hi, for example h1 and h2 would have the next values.
h1 =
1.1604
-0.2671
h2 =
1.9483
-1.8290
And I want to insert them and replace the zeros at the vector xh.
please explicitly state your desired output

Something like this?
%%
N = 50;
xh = zeros(2,N);
%% Insert h1 and h2 into xh
for jj = 1 : 2 : N
...
[h1,h2] = cruza(x(:,p1),x(:,p2));
xh(:,jj) = h1;
xh(:,jj+1) = h2;
end
