Shivam723.m

The objective of this is todetermine the rate of change of temperature for 2881 timesteps. I am trying to run a for loop for each time step but I am getting an error saying that the index exceeds the array bounds.

Error in Shivam723 (line 164)

Tempchange1(i) = (a1*J_sun*Asun + e1*J_ear*Aearth -

e1*sigma*TPanel1(i-1)*Asat)/(satmass*sp_heat);

I found the solution.

TPanel(1:6) was defined early on.

The issue was that while the initial TPanel(i-1) value was being assesed, the TPanel (i-1) wasn't being saved for the next iteration. Hence why it stopped after the first loop. Correcting this error, and a few other small ones made the code work as intended.
