Which of the following is the correct syntax to interpolate values at points xq using vectors x and y?
Ainterp1(x, xq, y)
Binterp1(y, x, xq)
Cinterp1(x, y, xq)
Dinterp1(xq, x, y)
Step-by-Step Solution
Solution:

  1. Step 1: Recall interp1 function syntax

    The syntax is interp1(x, y, xq) where x and y are known data points and xq are query points.

  2. Step 2: Check option correctness

    Only interp1(x, y, xq) matches the correct order of arguments.

  3. Final Answer:

    interp1(x, y, xq) -> Option C

  4. Quick Check:

    Syntax = interp1(x, y, xq) [OK]
Quick Trick: Syntax order: x, y, then query points xq [OK]
Common Mistakes:
  • Swapping x and y
  • Placing query points second
  • Incorrect argument order
