How do I find the number of "struct" class in a structure array?

Hi,
Is there a way to determine the number of "struct" names in the structure array?
This way I could elimate the previous non-struct variables created.
Thanks

Hi Ferd maybe this will help. Let's say we defined a structure to hold a matrix, a cell, and a function. Could look like this:
s = struct %declare structure
s.someNumbers = [1, 2, 3] %add a matrix to the structure
s.someText = {'hello', 'world'} %add some text to the structure
s.someFunction = @(x) 2*x.^2 %add a function to the structure
Now, the function holds three different things. To get the names of these fields we can use
fieldNames = fieldnames(s)
To get the number of fields in the structure use
numFields = length(fieldNames)
