How to relabel the structures fields in a sequence?

I have a structure A which has 20 fields(bin_1 to bin_20), but i removed some field with null values. Now I am left with the following.

A = struct with fields:

bin_1: [14115×19 table]

bin_17: [9829×19 table]

bin_18: [11772×19 table]

bin_19: [14115×19 table]

Now I need program that converts the bin_ indices automatically to a sequence:

A = struct with fields:

bin_1: [14115×19 table]

bin_2: [9829×19 table]

bin_3: [11772×19 table]

bin_4: [14115×19 table]

Will really appreciate some help here. Thanks

You would not need to do this if you used a non-scalar structure. Better data design makes this problem disappear.

newfields = "bin_" + (1:length(fieldnames(A)));
A = cell2struct(struct2cell(A), newfields);

Thanks. This worked well for me.
