I have a column matrix of data , Temp_data= [20;27;29;33;40] , i want to subtract each element i, by the first element (i.e 20-20; 27-20; 29-20;33-20), how do i do this?
also, how to do the similar operation if i have to subtract consequtive elements, i.e A(n) - A(n-1) [ex: 20-20; 27-20; 29-27....]

Temp_data= [20;27;29;33;40]
Case_1 = Temp_data - Temp_data(1)
Case_2 = diff(Temp_data)
