Hello all,

Error message:

Warning: Name is nonexistent or not a directory: D:\Results\wind_data\150622

  In addpath (line 96) 
Undefined function or variable 'WindRose'.

Code:

clear all
close all
clc

cd('D:\Results\wind_data\');
addpath M:\Matlab_download\WindRose 150622;

M = xlsread('Crosby_wind.xlsx');

direction = M(552:887,1);
speed = M(552:887,3);

[figure_handle,count,speeds,directions,Table] = WindRose(direction,speed);
