How to create the following cell array with the following pattern quickly

Hi,

I would like to create the following cell array quickly without explicitly stating the elements as I am doing now:

marker = {'s','o','d','p','x','+','*','>', ...
          'o','d','p','x','+','*','>','s', ...
          'd','p','x','+','*','>','s','o', ...
          'p','x','+','*','>','s','o','d', ...
          'x','+','*','>','s','o','d','p', ...
          '+','*','>','s','o','d','p','x', ...
          '*','>','s','o','d','p','x','+', ...
          '>','s','o','d','p','x','+','*'}

As you can see there is a pattern here, there are 8 unique marker types and each consecutive group of 8 markers is based on the first 8 markers...I am new to matlab and would like to know if there is any intrinsic function that I could use or some sort of looping algorithm to create this cell array. I ask because I may need a larger cell array down the road and I think this is inefficient.

[EDITED, Jan, format improved]

After inserting some spaces, the pattern is obvious.

Okay so the first 8 markers are s,o,d,p,x,+,*,> The next 8 are o,d,p,x,+,*,>,s The next 8 are d,p,x,+,*,>,s,o and so on... do you see it now? I basically wanna use the 8 unique ones and loop through and concatenate the cell array with 8 markers on every loop and following that pattern.

The overall purpose is to create a 1 x n structure with 3 fields ... color, linetype and marker. color and linetype each had a repeating pattern of colors and linetypes so that was easy to concatenate using a loop. But the markers have this pattern which is not trivial (for me at least) to generate in a loop.

The final goal is to have a structure as follows: prop(1x1) = color = 'black' linetype = '-' marker = 's' prop(2x2) = color = 'red' linetype = ':' marker = 'o' etc etc...

You must have guessed the application of this. To apply these fields in a loop that generates a multiline plot with different properties for each line.

Thanks Jan...the way you formatted it is how I had formatted it on my code but couldn't get it to format it that way here

Answer 1

[Andrei Bobrov]

m = {'s'    'o'    'd'    'p'    'x'    '+'    '*'    '>'};
idx = hankel(1:numel(m),[numel(m) 1:numel(m)-1]);
marker = m(idx(:)');

[Oleg Komarov]

Another solution based on the circulant matrix:

idx    = fliplr(gallery('circul',numel(m):-1:1));
marker = m(idx(:)');

Excellent. Many thanks to Andrei and Oleg. I am going with the hankel solution since I do not understand the second one. I had not recognized that particular pattern in my cell array and even if I had, I would not have known about this hankel matrix (engineer!).

This was my first post on an online forum and I feel like I should've started using forums much earlier!
