HI, when I use this code in my exercise I don’t get the correct answer, but when I use the code from week 3 programming assignment to compute cost, I get the correct answer. Can somebody explain why?? Thank You

Hey @Syed_Hamza_Tehseen,

In your code, you have taken the transpose of `Y`

and `(1 - Y)`

. If say, the dimensionality of `Y = (1, m)`

, where `m`

is the number of examples; then in your opinion, what will be the dimensionality of `cost_1`

and `cost_2`

? Will that be `(1, 1)`

or `(m, m)`

? I hope this resolves your query.

Cheers,
