not getting output

hello @raghav007

check now->

#3

what is the reason for doing b[i-1] instead of b[i] in line 56

#4

in vector b , we have strored values starting from index 0.
but in f1 we are storing from 1 onwards thats why using i-1 for b

#5

but i stored it from 1 itself , are we supposed to store from 0

#6

no u r storing from index 0 only. check line 104, there u are using push back function becuase of that elements will be inserted from index 0 onwards

#7

ohh okay got it now .

are the values written in the matrices correct ? how is f(n) + f(n-1) equal to f(n+1)

#9

f(n)=f(n-1) + f(n-2)
REPLACE n with n+1
f(n+1)=f(n)+f(n-1)

#10

why isnt it written as below in front of the transformation matrix

f(n-2)
f(n-1)

the way Fi is written here in step3, why was it not written this way above too

#13

…

both are correct . . . . , both are represeting the same thing… .

its just first row become second and second row become first.

#14

oh okay I just started this topic today so it’s a bit confusing so as long as the relation is correct we can write terms in whatever order we want

#15

…

yeah expression must be correct. implementation will also vary accordingly.
