MATLAB Question:
im just trying to write some code to solve the following problem. if i have a matrix showing pressure losses at section intervals. Eg.
Loss= [ 2, 3, 4, 6] psi and a starting pressure of 400 psi
how would write a code that would produce a matrix showing the resultant pressure after the loss is applied:
eg. 400-2=398 psi 398-3=395 psi 395-4=391 psi 391-6=385 psi
giving a matrix: P_resultant = [398 395 391 385]
thanks!

P_resultant=cumsum([400 -Loss]);
P_resultant(1)=[]
