MATLAB version of the GSTA model

MATLAB version of the GSTA model (Gao, 1996) modified

This code is Grain Size Trend Analysis (GSTA), on the basis of the combined trend of the following types of trends (Gao, 1996) :

Type 1: Better sorted, coarser and more positively skewed
Type 2: Better sorted, finer and more negatively skewed.

Main code : GSTA2013_KNU.m
Input file : input.txt
Output file : OUT.txt, input_GSTA.csv
----------------------------------------------------------------
OUT.txt is the result of the original FORTRAN code proposed by Gao (1996).
Input_GSTA.csv is the result of this code.
