MATLAB - Numerical Methods

You want to fit a custom exponential model y = a*exp(b*x) to data vectors x and y. Which MATLAB command correctly fits this model?

Apolyfit(x, y, 1)

Bfit(x, y, 'exp1')

Cfit(x, y, 'poly2')

Dpolyfit(log(x), y, 1)

Step-by-Step Solution

Solution:

Step 1: Identify model type
Exponential model y = a*exp(b*x) matches 'exp1' in fit function.
Step 2: Use fit function with 'exp1'
Command fit(x, y, 'exp1') fits exponential model.
Final Answer:
fit(x, y, 'exp1') -> Option B
Quick Check:
Exponential fit uses fit with 'exp1' [OK]

Quick Trick: Use fit with 'exp1' for exponential models [OK]
