Get line of vector from struct array field
显示 更早的评论
Let's have a structure:
my_struct(1).my_field = [11;12];
my_struct(2).my_field = [21;22];
I want to get vector of first values of the field 'my_field', that is:
temp = [my_struct.field];
result = temp(1,:);
Is there any more elegant way which does not use temporary variable and might be coded into one line? Something like:
result = [my_struct.field](1,:); % produces error

No.
You could use arrayfun, but in my opinion this is much less elegant:
>> arrayfun(@(s)s.my_field(1),my_struct) ans = 11 21
