Sand Sieve Analysis (SANDY)

Script that allows you to know the main parameters of a sand sieve analysis

Sand Sieve Analysis
1. With this routine you can get the sand sieve analysis. Routine displays the computation of the particle-size distribution in different windows. Moreover, you can get the main parameters of statistics analysis: percentiles, mean, standard deviation, kurtosis, etc.
2. Inputs:
Instructions are on the code.
