hi i need help !
i have this problem :
if i run it he ask me what of all these function use i type 1 bcs my problem is it.After matlab starting and runing the first function
in a getCurrentAverage.m file that returns the N position vector with the current values in each YC product, the N position vector with the lowest values in each YMIN product, the N position vector with the highest values in each YMAX product and the N positions with average prices on each YA product.with using repeat FOR
