MATLAB: B = A(abs(diff(A))); i want to find the abs difference of 08 values

please help

08 values in a row i have to find the absolute differnce of these values any one help me like

A = [3,6,9,8,7,8,6,8]
B = A(abs(diff(A)));

THIS ERROR WILL BE SHOWN ubscript indices must either be real positive integers or logicals.

Error in CodeDriver (line 214) B = A(abs(diff(A)));

You've likely created variables named abs and/or diff. Rename those variables and you will be able to use the abs and diff functions again.

>> A=[-1,2,3,4,-5]
 B= [-6,-7,8,9,10]
   i1=A<0;
   i2=A>0;
   i3=B<0;
   i4=B>0;
         AA= A(i1 & i3)
          BB=B(i2 & i4)
A =
      -1     2     3     4    -5
B =
      -6    -7     8     9    10
AA =
      -1
BB =
       8     9

MATLAB: X.abs()

That is true, but it doesn't imply that x you declared will have abs as its method.

I think that claim you quoted means that MATLAB's data types are internally implemented as object-oriented classes. The double data type doesn't provide any method.

class(x) returns double
methodsview(x) causes an error.
