I have a se of array like 'a' and I would like to split them into

[1 2 3 4 5 6 7 8 9]

[17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42]

[50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73]

[79 80 81 82 83 84 85 86 87 88]

Then, it can be plot by using plot(x(a),y(a),'-')

I have go through the split array question but it cant work on these kind of array.

Can someone guide me on this? Will be much appreciate.

a=[1 2 3 4 5 6 7 8 9 17 18 19	20 21 22 23 24 25 26 27 28 29 30 
   31 32 33 34 35 36 37 38 39 40 41 42 50 51 52 53 54 55 56 57 58 59 60
   61 62 63 64 65 66 67 68 69	70 71 72 73 79 80 81 82	83 84 85 86 87 88]

L = [9 26 24 10] ;   % required lengths 
C = mat2cell(a,1,L);

Hi, your code works so fine but the length might be unknown as im using ginput. the 'a' array is just an example. Can it be done without knowing the length? Appreciate..
