*Algorithms and Data Structures in F and Fortran*
emphasizes fundamentals of structured programming
through study of F and Fortran 90/95.
It is designed for a reader's second exposure
to computer programming,
whether it be through self-study or a course
in computer science.

The book contains a detailed exposition on important algorithms, some traditional, some new. For most of these topics, no prior or special knowledge is assumed. Popular sort algorithms are examined; the Bubble Sort, Shell Sort, Heap Sort, Quicksort, and Hash Sort. Various search algorithms are studied: linear, binary, hash, and binary search tree. The chapter on recursion commences with some short examples and culminates with Quicksort and algorithms for space-filling curves. Algorithms for solving linear equations, including tri-diagonal and banded systems (Gauss, Gauss-Seidel), matrix inversion, and roots of polynomials, are covered in detail. Algorithms for performing Fourier Transforms are included. The significant string search algorithms studied include the Knuth-Morris-Pratt, Rabin-Karp, Boyer-Moore, Baeza-Yates-Gonnet, and Baeza-Yates-Perleberg. Graphics algorithms for creating fractals and space-filling curves, for creating picture files (PCX and TIFF files), for reading a PCX file, and data compression and expansion, are provided. The chapter on numerical methods includes basic algorithms for integration, differentiation, root-finding, least squares approximation, interpolation, and for solving differential equations. The adventurous will find that the large bibliography includes many works appropriate for further reading, study, or research.

The book is not just algorithms. Additional F/Fortran topics are included: separate theme chapter are devoted to complex arithmetic, file processing, list processing (the extensive chapter includes binary search trees), text processing including string searching, and recursion.

Chapters can be studied in any order, as they are mostly independent; They can be selected at will according the reader's interests.

The book is backed up by comprehensive appendices on the built-in procedures and summaries of the F and Fortran statements.

It is recommended, although not essential, that the reader be
familiar with the F or Fortrran 90/95 programming language,
prior to using this text.
One excellent introduction to F is
*Programmer's Guide to F*.
