I have the following code: if sol[5,i] - sol_1[5,i] >= 0.0 s[i] = sol[5,i] - sol_1[5,i] else s[i] = sol_1[5,i] - sol[5,i] end end Now, here, sol and sol_1 correspond to 2 solutions I have from DifferentialEquations.jl (basically, I would like to plot the absolute value …

Can you explain why you are using if/else instead of abs? It seems like a very particular, but odd, choice.

[image] Sh_166: the absolute value of the difference s = abs(sol[5,i] - sol_1[5,i]) You haven’t provided enough information for anyone to tell why your original code doesn’t work (suggested in the link in the other response). Maybe there’s something else in your loop overwriting s[i]. Som…

Ah, sorry. My code is quite large, so I skipped it (it takes time to run, and contains a lot of irrelevant portions). However, I did manage to figure it out (i.e. I managed to compute what I wanted), so there’s that.

Actually, I did at first. Must’ve made a typo there because it kept showing me error, so I went a more naive way. Anyhow, using abs.() works fine now, so I have just skipped the loop. Thanks a lot.
