Abstract of my project the main objective of the project is the development of an application in matlab program. If x and y have different lengths, the function appends zeros to the end of the shorter vector so it has the same length as the other. Cxcorra,b, where a and b represent samples taken over time interval t which is assumed to be a common period of two corresponding periodic signals. Crosscorrelation measures the similarity between a vector x and shifted lagged copies of a vector y as a function of the lag. R corrcoef a, b devuelve coeficientes entre dos variables.
