Is there any way to write down a one-line script for assigning values to a struct array with fields?
x(1).a=1; x(2).a=2;
I'd like to change each value to 10 and 20 respectively. (I mean x(1).a=10, x(2).a=20) [x.a]=[10 20]; <- This causes an error.

Hi,
>> x = struct('a',{10,20});
This will create x(1).a = 10 and x(2).a = 20
To modify an already existing structure array,
>> new_val = num2cell([10,20]);
>> [x.a] = new_val{:};

Thanks for your comment, Vandana. It works perfectrly! But I found that there is no way to assign struct array in one line. :-(
