help in doing forward and backward difference...

dv_dteta = zeros (length(crank_angle),1)
for j = 1:1:length(crank_angle-1) dv_dteta = (s(j+1)-s(j))./(crank_angle(j+1)-crank_angle(j)); end
when i write this i get an error code saying Index exceeds matrix dimensions.
the crank angle is a array of 300 data points.
is there a way to do a backward difference for the first point and the rest forward difference to match the dimensions???

You must use
j = 1:length(crank_angle)-1
rather then
j = 1:1:length(crank_angle-1)
