The Gaussian Copula function for finance has been totally discredited and you shouldn't touch it with a barge-pole. See The Formula That Sank Wall Street in Wired magazine.
There are many places where one can get a Gaussian Copula. One can get a Gaussian Copula at popular on the web sources such as Wired, UCL Finds, and SPS.
A zero copula is the joining of a subject to a predicate without the use of a copula, such as "the more the merrier".
In linguistics, a copula is a word or morpheme used to link a subject to its complement. It typically expresses the equality or identity of the subject and the complement. In English, the primary copula is the verb "to be" (e.g., "She is happy."), but other verbs like "seem," "appear," and "become" can also function as copulas in certain contexts.

Jon Gregory of BNP Paribas and Jean-Paul Laurent of Univeristy of Lyon and BNP Paribas in their paper, "In the Core of Correlation," indicate the appeal of the Guassian single-factor Copula Model relates to: (i) its ease of implementing via Monte Carlo simulation, (ii) the speed with which prices and deltas can be determined, and (iii) its underlying dependence structure has been linked to equity returns correlation.
A "copula" is a word used to link a subject and a predicate in a sentence. Common examples include "is", "am", "are", and "be".Accordingly, an example of such in a sentence would be:"I am glad to see you."or"The group is excited to have been accepted."In my personal experience, in English 101/102, simple or cliche use of copula is discouraged. Action verbs, instead, can be used in their place.Examples of sentence avoiding the standard use of copula:"Seeing you fills me with glee."or"The group revels in the news of your acceptance."Bottom Line: You use copula to link a subject with other subjects, verbs, adjectives, etc. In writing it may be beneficial to use actions to connect the sentence. They too are copula, it just sounds better.

Copulas are an exremely useful tool used to build models of the joint behavior of multiple financial variables. They allow you to define a multivariate statistical distribution in two steps:first you specify the marginal univariate distribution for each of the variables of interestthen you link the single univariate distributions via a copula in order to obtain a multivariate distributionBasically, what the copula does is to specify the structure of the dependence among the variables, leaving their marginal distributions unaltered. Mathematically, a copula is a scalar-valued function of n-variables. If you plug n univariate distribution functions into its n arguments you get a multivariate distribution function, which has the original n distribution functions as its marginals. Stated more formally (for the case of two variables), if C=C(u,v) is the copula and F(x) and G(y) are two univariate distribution functions, H=H(x,y)=C(F(x),G(y)) is a bivariate distribution function having C and G as its marginals.
