Gini coefficient and the Lorentz curve

Computes the Gini coefficient and the Lorentz curve of weighted data.

Description

The Gini coefficient is a measure of the inequality of a distribution (often used for income or wealth distributions). The Lorentz curve is a graphical representation of this inequality which is intimately related to the Gini coefficient. The program is straightforward to use. Please consult the help included in the file for an extensive description of the two concepts and how to use the program.

The progrma gives me a error
??? Error: File: gini.m Line: 96 Column: 7
Expression or statement is incorrect--possibly
unbalanced (, {, or [.

Dear Duarte, this is odd, because line 96 is "[~,ord] = sort(val);", and that is a perfectly valid statement. If you have an older version of Matlab, try replacing the tilde as follows: "[temp,ord] = sort(val);" and let me know if that helps.
