Description

Matlab programming, discerete convolution and deconvolution, Hadamard's conditions of well-posedness, minimum norm solutions, singular value decomposition (SVD) and condition number, Moore-Penrose pseudoinverse, truncated SVD, Tikhonov regularization

Learning outcomes

After the course student
  • Understands discrete convolution as a matrix model
  • Learns least-squares solution technique and see that it can be numerically unstable
  • Shows how to use SVD to detect ill-posedness in a matrix-based inverse problem
  • Understands why deconvolution needs special regularised methods
  • Knows how to write robust Matlab algorithms for signal deconvolution and image deblurring

Description of prerequisites
