Kanti Bhushan Datta, Ph.D., D.Sc., FNAE, served for 19 years (1982–2001) in the Department of Electrical Engineering, Indian Institute of Technology Kharagpur where he remained Professor from 1985 to 2001. Earlier, his another major tenure for 17 years (1965–1982) had been in the Department of Applied Physics, University of Calcutta.Although an electrical engineer by profession, his mathematical background and research in Theory of Control Systems (where one encounters linear algebra problems in abundance) motivated Dr. Datta to present his experience in mathematics in a book entitled Matrix and Linear Algebra, published in 1991, and whose second edition now includes MATLAB for the study of the numerical aspect of matrix theory.
