Hi, I think you are looking for this:

s=rmfield(s,field)

example of use:

s.a=1;
s.b=2;
s.c=3;

>> s

s = 

      a: 1
      b: 2
      c: 3

s=rmfield(s,'a');
>> s

s = 

      b: 2
      c: 3

[David Sanchez]

you can use it recursively in the struct array

s1=struct('a',num2cell(1:10),'b',num2cell(11:20),'c',num2cell(21:30))
