how to concatenate the two variables.?

how to concatenate the two variables a(1*5) cell and b(3*5) double

   ex:
         a=  ch1_01   ch1_02   ch2_01   ch2_02   ch3_01  

        b=
            12.2172  83.1253  32.3429  73.2126   43.3222
           32.2179  13.1213  42.3388  53.5127   52.1229
           82.2571  43.1231  52.1400  33.4129   44.3326

output: in one variable as 

           ch1_01   ch1_02   ch2_01   ch2_02   ch3_01
           12.2172  83.1253  32.3429  73.2126   43.3222
           32.2179  13.1213  42.3388  53.5127   52.1229

Sandy, you could do:

 a = {'ch1_01' 'ch1_02' 'ch2_01' 'ch2_02' 'ch3_01'};
 b = [12.2172  83.1253  32.3429  73.2126   43.3222;...
      32.2179  13.1213  42.3388  53.5127   52.1229;...
      82.2571  43.1231  52.1400  33.4129   44.3326];
 c.col = a;
 c.val = b;

To access the different components use, e.g.,

 c.col(2)
 c.val(1:2,2:3)

thanks..how to save this structure variable as an excel file??

[Mischa Kim]

This should do:

 filename = 'testdata.xlsx';
 sheet    = 1;
 xlswrite(filename,c.col,sheet,'A1')
 xlswrite(filename,c.val,sheet,'A2')
