The Complete Course of Fortran Programming

Install and configure the gfortran fortran compiler on Linux, Windows, and Mac. Write a minimal F90 program, compile with gfortran, and run it locally or online.

Set up and configure Fortran IDE environments using VS Code and Emacs, install Python, add environment paths, install Fortran plugins and code runner, configure build tasks, and test GFortran compilation.

Discover how IDEs accelerate Fortran coding with tab-triggered autocomplete and snippets in VS Code and Emacs. Learn to configure a linter, manage declarations, and fix errors highlighted by squiggly lines.

Explore Fortran syntax, including fixed and free formats, line continuation, case-insensitive rules, and basic output formatting with field width and format specifiers.

Explore standard output in Fortran by using intrinsic print and write, learn default formatting, and design custom format specifiers to neatly align strings and numbers on the screen.

Learn to use standard input in Fortran with the read statement, mirroring standard output, and read multiple values via a director list, while understanding implicit data type rules.

Learn how Fortran uses iostat to handle input and output errors, checking status after read and write to distinguish success (zero) from failure (non-zero).

Explore the four core programming constructs, namely assignment, selection, sequence, and iteration, in Fortran, focusing on if statements, end if, nesting, and program control flow with grade mapping examples.

Explore the Fortran select case statement, compare it to C's switch, handle multiple data types except real, show default and end select, and note absence of a break.

Master looping structures in Fortran, including do, do while, exit, and cycle, through syntax, initialization, stepping, and breaking conditions, with nested loops and practical demos.

Explore conditional statements and loops, including do and do while, and examine goto as a jump tool, with exit and stop for program termination.

Explore arrays in Fortran, linking memory to a variable that holds values, accessed by 1-based indices. Learn to declare, initialize, and extend from one-dimensional to 2D and 3D arrays.

Learn how to declare and initialize one-dimensional arrays in Fortran, including integer, real (double precision, kind eight), logical, and complex types, and print their elements or the whole array.

Learn to declare, initialize, and reshape data into multidimensional arrays or matrices in Fortran, map vectors to 2d grids with the reshape command, and access elements via loops.

Explore array and matrix operations in Fortran, including indexing, reshaping, slicing with strides, concatenation, reductions like sum and max, custom search, broadcasting, and element-wise comparisons.

Explains the key features of procedures, including reusability, modularity, maintainability, and readability, and distinguishes subroutines from functions, including how subroutines execute on call and functions return values.

Learn the differences between subroutines and functions in Fortran, including syntax, parameters, end subroutine and end function, and the return and result concepts, plus how intent and out are used.

Explore parameters and arguments in Fortran, learn how pass by value and pass by reference differ, see how the value keyword prevents updates outside a subroutine, and understand contains blocks.

Explore modules and program units in Fortran, encapsulation and data security, and how to organize subroutines and functions into modules for reusable, maintainable code, with multi-file compilation in gfortran.

Compare static and dynamic memory in Fortran, show how to allocate and deallocate allocatable arrays and matrices at runtime, and highlight memory management to avoid leaks.

Explore Fortran pointers and memory management, including allocating and deallocating memory, pointer assignment with redirection, null initialization, and avoiding memory leaks and dangling pointers.

Explore dynamic memory allocations in Fortran by using pointers to custom types, declaring types, allocating and accessing attributes, and deallocating to prevent memory leakage.

Explore built-in Fortran math functions, including absolute, square root, exponential, logarithms, and trigonometric and hyperbolic functions. Learn scalar and array operations, matrix multiplication, transpose, and reductions like min and mean.

Explore numerical computation in Fortran by applying integration with the trapezium rule and differentiation to estimate areas under curves and rates of change, highlighting precision through finer intervals.

Learn how to implement interpolation and curve fitting in Fortran, using linear interpolation, extrapolation, and linear regression to model data with x and y values.

Explore how file descriptors 0, 1, and 2 map to keyboard, display, and error streams across Linux, Windows, and Mac, and how Fortran units correspond to system descriptors.

Learn how to write data to a file in Fortran by opening a file descriptor, selecting replace or old modes, and handling text and binary data with inquire checks.

Explain how to read data from text, binary, and object-formatted files in Fortran, including file existence checks, opening modes, reading a 3 by 3 matrix, and validating reads.

Explore file handling and data processing in Fortran by reading and writing student grade data, computing averages, and visualizing results with gnuplot.
