Linear Interpolation in a Design Table: Bracketing Rows, INDEX/MATCH & Out-of-Range Flags
This lesson is part of the course
In this lesson
You read a fictional strength factor at 235 °C from a table that only lists every 50 °C: find the bracketing rows with MATCH, fetch x₁, x₂, y₁ and y₂ with INDEX, interpolate, and count the temperatures that lie outside the table.
