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)

Exactly what was needed!

Thanks!
