function alt_km=ITU_P1511(lat,long) computes altitude of a site at given lat,long coordinates by means of bicubic interpolation using itu topo 0.5 degrees resolution matrix. refer to ITU-R Recommendation P 1511. INPUTS lat: latitude + = North, -=south long: longitude, positive degrees East. Required data: TOPO_0d5.txt, available from the ITU-R SG3 software site http://www.itu.int/ITU-R/study-groups/soft...-topography.zip http://www.itu.int/ITU-R/index.asp?categor...nk=rsg3&lang=en example of usage: alt_km=ITU_P1511(52,0); %somewhere in the UK Luis Emiliani.

ecdfcalc4fe calculates absic statistics for a sample set: mean, variance, std.dev, kurtosis, skewness, probability mass function/density funcion and cumulative distribution. it does not provide new algorithms but combines current function on the statistical toolbox to ease things a bit simple to use, just input the data, binsize (either normal or skewed for specifically recommended insize according to expected distribution shape or a value manually entered), and whether you want to plot or not the results.

function [P R]=Global_Moupfouma(Rzz1,ClimZone) Function implementing the Global Moupfouma model, As per Electronic Letters paper "Point Rainfall rate cumulative distribution valid at various locations" F. Moupfouma and L. Martin, EL, Vol.29, No.17, Aug. 1993 Inputs Rzz1: Rain rate value exceeded 0.01% of the time A coarse classification is used (Temperate, Tropical) OUTPUTS P: vector of percentages of exceedande. R : vector of rain rate values exceeded during P percent of the time {P,R} are a cumulative distribution function useful for telecom system design at frequencies above 7 GHz in tropical regions, or in general, for systems affected by rain attenuation Example of usage: [P R]=Global_Moupfouma(110,'tropical')
