How to create multiple matrix using for loop?

Hi all, I am having y=[1 2 3 4 5 6 7 8 9 10] as data. i want to write array x1 =[ 1 2 3 4 5] x2 =[2 3 4 5 6] x3= [3 4 5 6 7] like this upto x6 =[6 7 8 9 10]. please help me to create this using matlab. I tried as follows :n=10;k=6;m=5; for i=1:k for j=i:i+m-2 x[i]= a(j); end end but it is not working!!

Answer 1

ya = [1,2,3,4,5,6,7,8,9,10];

for iy = 1:(length(ya)/2)+1
    xa(iy,:) = ya(iy:4+iy);
end

Answer 2

 y=[1 2 3 4 5 6 7 8 9 10]
x = y([1:5;2:6;3:7;4:8;5:9;6:10])

Answer 3

Hi..

try this code

a=[1:10];

for i=1:numel(a)

    if i==a(1)

        disp(a)

    elseif i<=6

        a(1)=[];

        disp(a) 

    else

        break;

    end

end

Thanks liham Hardy

when i use same logic for long data i got subscripted assignment diamentiopn mismatch error.eg. i wrote the code as t=-pi :0.01244:pi y=sin(t) n=length(y); m=n/2;k=n+1-m; for iy=1:k; xa(iy,:)=y(iy+m-1); end disp(xa). I want a sine wave of 504 samples ,add it with White guassian noise.then write sampled sine wave in terms of lagged vectors and then finally the trajectory matrix.
