👉Practical Examples of SciPy Functions

👉1. File I/O Operations

SciPy supports various file formats like .mat, .csv, .txt, and more.

Example: Saving and Loading .mat Files

python

import numpy as np

from scipy import io as sio

array = np.ones((4, 4))

sio.savemat(‘example.mat’, {‘ar’: array})

data = sio.loadmat(‘example.mat’, struct_as_record=True)

print(data[‘ar’])

Output:

lua

[[1. 1. 1. 1.]

 [1. 1. 1. 1.]

 [1. 1. 1. 1.]

 [1. 1. 1. 1.]]

---

👉2. Special Mathematical Functions

Cubic Root Example:

python

from scipy.special import cbrt

print(cbrt([27, 64]))

Output:

csharp

[3. 4.]

---

👉3. Linear Algebra Operations

Finding Matrix Determinant:

python

from scipy import linalg

import numpy as np

matrix = np.array([[4, 5], [3, 2]])

print(linalg.det(matrix))

Output: -7.0

---

👉4. Fast Fourier Transform (FFT) Example

Visualizing Sinusoidal Waves with FFT:

python

from scipy import fftpack

import numpy as np

import matplotlib.pyplot as plt

# Sample Wave

frequency = 5  

sample_rate = 50  

t = np.linspace(0, 2, 2 * sample_rate, endpoint=False)

wave = np.sin(frequency * 2 * np.pi * t)

# FFT Analysis

A = fftpack.fft(wave)

frequencies = fftpack.fftfreq(len(wave)) * sample_rate

plt.stem(frequencies, np.abs(A))

plt.xlabel(‘Frequency (Hz)’)

plt.ylabel(‘Magnitude’)

plt.show()

---

👉5. Image Manipulation with SciPy

Rotating an Image:

python

from scipy import ndimage, misc

import matplotlib.pyplot as plt

image = misc.face()

rotated_image = ndimage.rotate(image, 135)

plt.imshow(rotated_image)

plt.show()
