Webb26 dec. 2024 · 3 Answers Sorted by: 2 I would use interp1 to find the value. I'll assume that your x variable is called x and your cdf value is called c. You can then use code like this to get the x value where c = 0.9. This will work even if you don't have a cdf value at exactly 0.9 x_at_0p9 = interp1 (c, x, 0.9); Share Improve this answer Follow Webb17 nov. 2024 · Kurva-S atau S-Curve adalah suatu grafik hubungan antara waktu pelaksanaan proyek dengan nilai akumulasi progress pelaksanaan proyek mulai dari … practitioners office definition https://decemchair.com
