Reliability analysis using Cronbach’s alpha

I’ve written a Matlab function, which calculates the Cronbach’s alpha between some items and do the if item is deleted process. this function will automatically delete the item which increase the Cronbach’s alpha maximally. before entering in if item is deleted process it checks the initial Cronbach’s alpha. if the Cronbach’s alpha value was greater…

Random walk movement

In this project, I wrote a matlab code to keep a marker which moves randomly toward a square area, inside the boundary. so the marker moves with a specific speed in a random direction. when the marker reaches to the boundary of the square area, it will first bounce back and then will keep moving…
