How can I remove all fields which start with a certain string?

I have a struct which contains fields (for example):
How can I remove all fields which start with 'shufling_significance_pos_slices'?
Thanks in advance

You would do much better do avoid naming the fields like this anyway. Confusing data and the abstract variables that represent them is the source of many bugs in beginners' programming. When you realize that 5, 10, etc are also data in their own right then your code will become a lot simpler.
Here is a discussion of why it is a bad idea to include meta-data (such as an index) in a variable name:
Then, once you realize that data does not belong in a variable name, simply create a non-scalar array and store all of your data in that:
S(1).index = 50;
S(2).index = 25;
S(3).index = 15;
S(4).index = 10;
S(5).index = 5;
S(1).shuffling_significance_pos_slices = ...
S(2).shuffling_significance_pos_slices = ...
then to entirely remove any field/s from the entire structure it requires just one simple command rmfield:
S = rmfield(S,'shuffling_significance_pos_slices');
That is how easy using MATLAB can be when the data is organized well!
