⟩ A question about matlab functioni have used diff(y,x) for a function in matlab and it has give me a answer that has abs(a,b) in it.wht is this function according to its two arguments?ali 08-1-2016?
diff(y) means calculates differences between adjacent elements of y along the first array dimension
y= [1 1 2 3 5 8 13 21];
z=diff(y)
z =
0 1 1 2 3 5 8
this is the difference between the adjacent columns (second column-first column) and the result of diff function that is number of column of z is one less than the number of column of y
diff(y,x) where x=2
diff function will call two times (x times)
y= [1 1 2 3 5 8 13 21];
x=2;
z=diff(y,x)
z= 1 0 1 1 2 3
number of column of z is two less than y
