This textbook introduces and explains numerical techniques relevant to engineering and science, along with program implementations in C, C++ and MATLAB. Topics typically include:

• Approximations, errors and computation basics

• Algebraic & transcendental equations

• Simultaneous linear systems & matrix inversion

• Curve fitting & interpolation

• Numerical differentiation & integration

• Solutions to ordinary & partial differential equations

• Linear programming

• Numerical algorithms with examples in C, C++, and MATLAB

Its combination of theory and practical programming makes it suitable for both classroom learning and self-study for engineering students, especially where numerical methods are part of the curriculum.
