,Question 1. Which MATLAB® command is typically used to generate a linearly spaced vector?
A) linspace()
B) range()
C) span()
D) vector()
Answer: A
Explanation: The linspace() function in MATLAB® creates a vector with linearly spaced points, which is
fundamental for setting up discretizations in inverse problems.
Question 2. In Python, which library is most commonly used for numerical linear algebra operations relevant to
inverse problems?
A) pandas
B) NumPy
C) matplotlib
D) SciPy
Answer: B
Explanation: NumPy provides efficient array operations and linear algebra routines essential for solving inverse
problems in Python.
Question 3. Which term describes the process of formulating an inverse problem where the goal is to recover
model parameters from observed data?
A) Forward modeling
B) Data assimilation
C) Inversion
D) Prediction
Answer: C
Explanation: Inversion involves estimating model parameters from data, which is central to geophysical data
analysis.

, Question 4. Which probability distribution is most appropriate for modeling measurement noise with known
variance?
A) Poisson distribution
B) Normal (Gaussian) distribution
C) Exponential distribution
D) Uniform distribution
Answer: B
Explanation: The normal distribution models measurement noise with known variance, assuming errors are
symmetrically distributed around zero.
Question 5. In the context of inverse problems, what does the least squares method aim to minimize?
A) The maximum likelihood
B) The sum of squared residuals
C) The absolute residuals
D) The entropy
Answer: B
Explanation: The least squares method minimizes the sum of squared differences between observed and
predicted data, providing an optimal solution under Gaussian noise assumptions.
Question 6. Which matrix operation defines the Moore-Penrose generalized inverse?
A) Pseudoinverse calculation
B) Eigenvalue decomposition
C) Singular value decomposition (SVD)
D) QR decomposition
Answer: C
Explanation: The Moore-Penrose pseudoinverse is computed via singular value decomposition, enabling
solutions to ill-posed or non-invertible systems.
Question 7. The maximum likelihood estimate (MLE) for a linear inverse problem with Gaussian noise is
equivalent to which method?
