Hello, I have been using “for” loop to calculate Internal Rate of Return (irr) for a range of investment options (t below represents option t in array of data) and attempted the codes below: for t in 1:nb a(t) = irr([-Market_values[:,t];AssetsCF[:,t]]) b(t) = irr([-Market_values[:,t];PDCF_annual…

Hard to say what’s going on without a reproducible example, but sounds a bit like a scope issue - if you create variables in a loop, they won’t generally be accessible outside the loop. Further, your a(t) notation looks a bit odd - from what you’re doing it looks like you’re trying to index into an…

please kindly start your code block with ```julia and close it with ``` right now it is very hard to read

Thanks, I think you are right it seems a scope issue. I have two “for” loop statements which I posted the first one as above. When I moved the “end”, the error message " IRR_MVCF not defined" disappeared. Unfortunately, the similar error message appeared. I think the issue here is how to define arr…

Sorry for not being clear. …Julia for t in 1:nb a(t) = irr([-Market_values[:,t];AssetsCF[:,t]]) b(t) = irr([-Market_values[:,t];PDCF_annual[:,t]]) c(t) = irr([-Market_values[:,t];FSCF_annual[:,t]]) IRR_MVCF = collect(a(t)) IRR_PDCF = collect(b(t)) IRR_FSCF = collect(c(t)) IRR_adj = IRR_MVCF -…

The code above still has a(t) rather than a[t]? The error is telling you that you’re trying to get the adjoint of a zero-dimensional array: this probably happens on this line: d(n) = npv(dot(IRR_adj'[n,:],ones(1)),vcat(0,AssetsCF[:,n])) where I assume IRR_adj is zero-dimensional. Again it’s …

Thank you Nilshg. I appreciated that the information I provided in my question wasn’t that clear as a couple of others suggested. But you have been so helpful to resolve my issue. Very much appreciated! Have a lovely day! Cheers, Ping.

Thank you for the tips, Josuagrw. Regards, Ping.
