title: Deleting multiple rows from all fields of a given structure array using Matlab
body: <p>I'm working on a structure with 12 fields, each consisting of a 1350x1 double.
  I want to delete all rows of all fields, given a condition regarding one of those fields, and come up with a new structure, still 12 field but of only 1150 rows.</p>
  
  <p>I don't mind the change of index, since one of these fields is a "Time" field to index the others.</p>
  
  <p>To clarify, my structure is called sens, and the fields are sens(1).Time, sens(1).Temp, sens(1).Humidity and so on.
  I want to find a value in sens(1).Time, define it as threshold value, and delete all rows smaller than this value, in all fields.</p>
  
  <p>I know it's possible by going through all field names, but been looking for a faster way as the names of the fields and/or the structure vary.</p>
  
  <p>Thank you.</p>
