c_ftcurvpi(3NCARG)

✨ c_ftcurvpi ✨ (from the NCAR GRAPHICS manual, bestie 💖)

🎀 NAME 🎀

c_ftcurvpi — the girl whose whole job is calculating integrals for periodic functions. no cap. 💅

🧚 FUNCTION PROTOTYPE 🧚

int c_ftcurvpi (float, float, float, int, float [], float [], float *);

🌸 SYNOPSIS 🌸

int c_ftcurvpi (xl, xr, p, m, xi, yi, integral);

💖 DESCRIPTION 💖

okay so here's the whole cast, let me introduce you 🫶

• xl — the lower limit of the integration. like, where we start, bestie.
• xr — the upper limit of the integration. where we stop. iconic duo with xl fr.
• p — the period of the function. ⚠️ important: p must not be less than xi[n-1] - xi[0]. not negotiable, she will not be flexible about this.
• m — the number of input data points. (N > 1, always)
• xi — an array holding the abscissae for the input function.
• yi — an array holding the functional values of the input function (y(k) is the functional value at x(k) for k=0,n).
• integral — the integral of the function from xl to xr gets handed back to you through *integral. she delivers. 💌

🔥 RETURN VALUE 🔥

c_ftcurvpi returns an error value, as per:

• = 0 — no error. slay, we ate, everything's perfect ✨
• = 1 — if n is less than 2.
• = 2 — if the period is strictly less than the span of the abscissae.

👑 USAGE 👑

c_ftcurvpi gets called after all of the desired values for control parameters have been set using the procedures c_ftseti, c_ftsetr, c_ftsetc. order matters, bestie, don't skip ahead 😭

the control parameters that apply to c_ftcurvpi are: sig.

🦋 ACCESS 🦋
