Pick a value from a matrix to produce another value in a matrix, and loop it

1 visualizzazione (ultimi 30 giorni)
Im trying to fill a matrix with values using previous values within the matrix, however i cant make it loop so that it fills up a row, so far i have
h21=H(2,1)
h11=H(1,1)
h12=2*a*h21+(1-2*a)*h11+(a-B/(2*rw))*((dr*Q)/(pi*rw*T)
H(1,2)=h12
but i want to make it more general so it picks sequential j values from a row in a matrix and enters it in the j value after it (i.e. j+1), i was thinking it would look something like this but it isnt working:
h2j=H(2,j)
h1j=H(1,j)
h1jplus1=2*a*h2j+(1-2*a)*h1j+(a-B/(2*rw))*((dr*Q)/(pi*rw*T))
H(1,j+1)=h1jplus1

Hi,
You can generalize it by using arrays and loops as follows:
H = [1 2 3 5; 4 5 6 5; 7 8 9 5]; % let
a = 1;
% Changing values of 1st row
for j = 1:size(H,2)-1
h21=H(2,j)
h11=H(1,j)
h12= a*h21+(1-2*a)*h11;
H(1,j+1)=h12
end
