i'm reading some data from xml file (can be any length). 
i can read the length of it.
each item/row in xml file is transfered to a struct data type in matlab.

i wanna initialize some variables to the the length of the data and put the data to a specific variable according the struct information.

how to initialize array of structs - sets all the values to zero?

one of the solutions

     s.a=zeros(1,4);
     s.b=nan(1,5);
     s(1:5)=s;
     s.a
%{
     ans =     % <- s(1).a
     0     0     0     0
     ans =
     0     0     0     0
     ans =
     0     0     0     0
     ans =
     0     0     0     0
     ans =
     0     0     0     0
%}

When you use struct() to declare the field names, if you use {} around the 
values, then as many struct array members will be created as there are values 
in the cell, with each member set to the cell value.

 >> struct('foo', mat2cell(zeros(5,4),ones(5,1)))
ans =
5x1 struct array with fields:
     foo
 >> ans(3).foo
ans =
      0     0     0     0
