In Shamir threshold scheme one that is called dealer, chooses the key and then shares some partial information about it, called among the participants, secretly. In this paper, we use some numerical methods with piecewise constant basis functions in Shamir threshold scheme. We first introduce operational matrix of this functions and then show how dealer multiplies this matrix by vector of shares to obtain a new vector and distributes it
