NNGETSLOPES(3NCARG)

✨ NAME ✨

NNGETSLOPES — bestie, this one grabs the slope at a coordinate you pick. That's it, that's the whole job 💅

This page lives in the NCAR GRAPHICS manual, section 3NCARG, and it's giving very much "small but mighty" energy.

---

🌸 SYNOPSIS 🌸

CALL NNGETSLOPES (I,J,SLOPE,IER)

---

💖 DESCRIPTION 💖

Okay so here's the tea on every single argument, no skips, no skimming 🫶

• I — (Integer, Input) — a subscript that indexes the first dimensioned variable in the output grid from the most recent call to NATGRIDS.
• J — (Integer, Input) — a subscript that indexes the second dimensioned variable in the output grid from the most recent call to NATGRIDS.
• SLOPE — (Real, Output) — the slope at the grid point Z(I,J), where Z is the output grid from that most recent call to NATGRIDS. Yes, it's that Z. The one you just made. 👑
• IER — (Integer, Output) — the error return value, aka the vibe check. If IER comes back as 0, then no errors were detected, we're slaying, everything's fine ✨. If IER is non-zero, then go read the man page for natgrid_errors for the details — it'll tell you exactly what went sideways 😭

Heads up bestie: I and J are indexing into the output grid from the most recent call to NATGRIDS. So like, don't be out here referencing some ancient grid from three calls ago, it's not gonna work out 💀

🎀 ACCESS 🎀

To use NNGETSLOPES, load the NCAR Graphics library ngmath. That's the one. Load it. 🧚
