Program Code – Mastering Curve Fitting in Coding

import numpy as np
import matplotlib.pyplot as plt
from scipy.optimize import curve_fit

# Define the function to fit (e.g., a linear function)
def func(x, a, b):
    return a * x + b

# Generate synthetic data for demonstration: y = 2x + 5 with some noise
xdata = np.linspace(0, 4, 50)  # 50 points from 0 to 4
y = func(xdata, 2, 5)
np.random.seed(0)  # Ensure reproducible results
ydata = y + np.random.normal(size=xdata.size)

# Curve fitting
popt, pcov = curve_fit(func, xdata, ydata)
a_fitted, b_fitted = popt

# Plotting original data and fitted curve
plt.figure(figsize=(6, 4))
plt.scatter(xdata, ydata, label='Data')
plt.plot(xdata, func(xdata, *popt), 'r-', label=f'Fitted Curve: y = {a_fitted:.2f}x + {b_fitted:.2f}')
plt.title('Curve Fitting Example')
plt.xlabel('X')
plt.ylabel('Y')
plt.legend()
plt.show()

### Code Output:

The program will plot a scatter plot of the synthetic data and a red line representing the fitted curve. The title of the plot is ‘Curve Fitting Example’. The X and Y labels correspond to the x and y axes, respectively. A legend is present, displaying ‘Data’ for the scatter plot points and ‘Fitted Curve: y = 2.00x + 5.00’ (or similar values considering the noise) for the curve.

### Code Explanation:

This code exemplifies mastering curve fitting in programming, using Python’s SciPy and matplotlib libraries. The process can be broken down into several key steps:

1. Function Definition: func(x, a, b) represents the model we’re fitting to the data. It’s a straight line with slope a and intercept b.
2. Data Generation: xdata is an array of 50 points between 0 and 4. y calculates the true output based on xdata, and ydata introduces some noise to simulate real-world data with np.random.normal.
3. Curve Fitting: curve_fit(func, xdata, ydata) applies the least squares method to find the best-fitting curve. It returns the optimal values for a and b (popt) and the estimated covariance of popt (pcov).
4. Plotting: The script then plots both the original data (plt.scatter) and the fitted curve (plt.plot) with appropriate labels and legends. *popt unpacks the optimal parameters found by curve_fit into the func for plotting.

The heart of this script lies in the curve_fit function, which intelligently adjusts a and b in func(x, a, b) to minimize the discrepancy between the modeled values and the observed data (ydata). This showcases how curve fitting can be utilized to understand and model relationships within datasets effectively.
