But this is still periodic.

comment Making a uniform histogram by random numbers
Thanks. Limited variation is acceptable as long as the histogram looks uniformly distributed despite minor variation. However, I am not sure whether the number of added elements remain minimum or not. Please not that, this is going to be applied on large number of sets which are not similar in terms of their number of values but their values remain with in the range. The ultimate result would be a uniform histogram for all the sets with minimum random elements such that all the histograms look relatively the same.

comment Making a uniform histogram by random numbers
Thanks. But This does not seem to be efficient since how I can get that minimum correctly?. Unless, I count all the bins find an average and fill all the bins to that average is what I thought but it is not efficient either. Is there any way such that I can do this by a PDF or something like that?

@Hennings: I also try again to clarify the question more. Let me give you an example of usage. Assume you need to create a matrix R that is used in a computation( let say you need to compute R*X where X is a variable matrix) however, R should not be changed in order to have the desired results. The requirement is that you are not allowed to store R but you are given 3 matrices( at beginning) that you can use to calculate R and later you might not have access to all of three to calculate R. Thus, you need to find a way that allows you to compute R by at least two of Is if you missed one of them

@HagenV: Thanks. With this solution I still can not reconstruct the R.

@HagenV: Thank. I am looking for the function f as you described with the condition that R should not reveal anything about Is and their combinations and G(R,I2,I3)--> T or G(R,I1,I3)--> T or G(R,I1,I2)--> T and T is the parameter that I use in my computation as a key type of thing

Thanks. We do not have 3 users here. Actually we have 3 secrets I1, I2, and I3 and we want to create R out of these three that can be used in a computation. However, R is generated on the fly and it is not stored anywhere. However, if we have access to two of the Is, we should be able to reconstruct the R such that it is "impossible" to find R with only one of the cyphers it is possible to find R by combining any two of the cyphers.

Thanks for your comments. However, I do not have R. I do have 3 Is but not R and wants to find R such that it is "impossible" to find R with only one of the cyphers and it is possible to find R by combining any two of the cyphers.
