hi!
i have a vector
%
A=[1 2 3 98 99 102]
i calculate the difference betwen thelement with the function diff
%
B=[ 1 1 95 1 3]
how could i manipulte vector A in this manner
%
BB=[A(1) A(1)+B(1)*5 A(2)+B(2)*5 A(3)+B(3)*5 ....A(5)+B(5)*5]
Thank you!

A=[1 2 3 98 99 102];
BB = [A(1) ( A(1:numel(A)-1) + diff(A) ).*5]

... which is mathematically the same as
[A(1) A(2:numel(A))*5]
So, no need for diff(A) at all!
