How to add an array (double) as a field to a struct variable?

I have a structure variable and want to add a field and fill the row with the values of an array (double). The following code works but isn't very nice. Is there a more elegant way to add a field including values without the use of the mat2cell function or a for loop?

field1 = 1:10
field2 = 4:13
%create struct with field 'start' with 10 values
A = struct('start',mat2cell(field1,1,ones(1,numel(field1))))
%transform field2 to cell 
temp = mat2cell(field2,1,ones([numel(field2),1]));
%add field 'end' with 10 values
[A(1:numel(field2)).end] = temp{:};
Solution

  • You can use num2cell rather than mat2cell which will (by default) place each element in it's own cell. Unfortunately, you will still need a temporary variable.

    A = struct('start', num2cell(field1));
tmp = num2cell(field2);
[A.end] = tmp{:};
