please ho can get in matlab B

please how can get in matlab value of B and how to write the equation B for example

w=1:1:360 how to get  B =sin(w2)- sin(w1) for each time step

[Azzi Abdelmalek]

What are w2 and w1?

[Jose Louis]

w2 and w1 are the values w for each time step , for example, w= [1 2 3 4 .....360] w2=2 and w1=1 for next step w2=3 and w1=2 etc

Either as a loop:

for w = 1:359
  B(w) = sind(w+1) - sind(w);  % SIND instead of SIN?!
end

or vectorized:

B = sind(2:360) - sind(1:259);

or most efficient:

B = diff(sind(1:360))

[Jose Louis]

thank you for your answer, I have one more question : w=15*(ts-12), w start from some value not from 1 to some value and the number of values 360 , how can make a loop from the first value of w to last value like this for w=15*(ts-12) B=diff(sind(1:365)) end
