Modify values in a struct array
显示 更早的评论
I would like to modify the values of a field of a struct array (without using a for loop). If my initial struct array is the following:
a.b(1).c = 5;
a.b(2).c = 5;
a.b(3).c = 5;
I would like to modify it such that:
a.b(1).c = 1
a.b(2).c = 2
a.b(3).c = 3
I thought that
[a.b.c] = [1:3]
would work, but it doesn't: Insufficient number of outputs from right hand side of equal sign to satisfy assignment.

newvalues = 1:3;
temp = num2cell(newvalues);
[a.b.c] = temp{:};
Unfortunately this is not easy to do on one line, at least not without using a helper function.
Expand = @(temp) temp{:};
[a.b.c] = Expand(num2cell(1:3));
