Vectors

This short code provides a Tanimoto distance calculator for binary vectors. It emulates the pdist function of the Statistics Toolbox which does not provide a Tanimoto distance option.

%Updated version $Date: May 18th,2011 by Liang Kuang at Stevens Institute of Tech%Update 1: Change int8 to int16 when current colormap is bigger than 64,which will cause error%Update 2: Added 'samesize' for making all the vectors the samesize%Update 3: Add colorbar corresponding the the magnitude...

This function will take a [1xn] or [mx1] vector and normalize it to a unit vector length.To use this function [vectorOut] = fcn_createUnitVector(vectorIn)Error checking is performed to test for NaN values in the output, and a square root of the sum of the squares == 1This function will take...

For vectors, WMEAN(X,W) is the weighted mean value of the elements in X using non-negative weights W. For matrices, WMEAN(X,W) is a row vector containing the weighted mean value of each column. For N-D arrays, WMEAN(X,W) is the weighted mean value of the elements along the first non-singleton...

mergesorted.m------------------If we have two individually sorted vectors "a" and "b" but they are not sorted with respect to each other and we want to merge them into vector "c" such that "c" is also a sorted vector. Then c=mergesorted(a,b) can be used.This function most likely make difference...

This is the package for online (competitive)/batch prediction using generalized linear models under square loss. The algorithms are derived using the Aggregating Algorithm.The algorithms have guarantees on the cumulative square loss for the worst case when applied in online fashion in comparison...

RanLip uses acceptance/rejection approach to generate random vectors, which is based on approximation of the probability density function from above with a "hat" function. It is assumed that the distribution hasLipschitz-continuous density, which is either given analytically or has a black box....

NDSPACE N-dimensionally spaced points NDSPACE(X1, X2) generates a column matrix of 10^n linearly equally spaced points in the hypercube defined by the two diametrically opposite cornerpoints X1 and X2 both n-by-1 vectors. If either is a scalar it will be expanded to repmat(X,n,1). NDSPACE(X1, X2,...

PP = PCHIPD(X,Y,D) provides the piecewise cubic polynomial which interpolates values Y and derivatives D at the sites X. This is meant to augment the built-in Matlab function PCHIP, which does not allow the user to specify derivatives.X must be a vector.If Y and D are vectors, then Y(i) and D(i)...
