Scramble the positions of a cell array

Question

I have two cell array as follows

Z=  (2,5) (2,3) (2,1) (2,2) (2,4)
    (4,5) (4,3) (4,1) (4,2) (4,4)
    (5,5) (5,3) (5,1) (5,2) (5,4)
    (3,5) (3,3) (3,1) (3,2) (3,4)
    (1,5) (1,3) (1,1) (1,2) (1,4)



W=  'ATGC' 'ACTG' 'AGCT' 'AATT' 'TATG'
    'GCTA' 'GACT' 'TACG' 'TGAT' 'ATAT'
    'TCGG' 'CATA' 'TAAT' 'TTTT' 'CTGC'
    'AAGT' 'AAGG' 'TGGG' 'TGTA' 'CAAA'
    'GTGG' 'CTCT' 'GATT' 'CGTG' 'CTGG'

Now i have a big problem....i need to create a new cell array 'G' where the value of W should be placed accprding to the positions given in Z.

For eg: The value at (2,5) in W ie;ATAT should be placed at (1,1) of G Both the cell arrays are just examples...i need to do it for a 256*256 array. Please help.Thanks in advance

Answer 1

If we presume the example as:

Z = {[2,5] [2,3] [2,1] [2,2] [2,4]...
    [4,5] [4,3] [4,1] [4,2] [4,4]...
    [5,5] [5,3] [5,1] [5,2] [5,4]...
    [3,5] [3,3] [3,1] [3,2] [3,4]...
    [1,5] [1,3] [1,1] [1,2] [1,4]}

W = {'ATGC' 'ACTG' 'AGCT' 'AATT' 'TATG';...
    'GCTA' 'GACT' 'TACG' 'TGAT' 'ATAT';...
    'TCGG' 'CATA' 'TAAT' 'TTTT' 'CTGC';...
    'AAGT' 'AAGG' 'TGGG' 'TGTA' 'CAAA';...
    'GTGG' 'CTCT' 'GATT' 'CGTG' 'CTGG'}

Then we got:

G = cell(5,5)

I = [Z{:}]; %indices in a vector
x = I(2:2:end); y = I(1:2:end);
I = sub2ind(size(Z),y,x);
G(I) = W(1:numel(W));
