If you can't find the specific book you're looking for, there are many excellent textbooks on computational methods for partial differential equations by other authors. Some popular ones include:
A critical aspect of Jain's work is the mathematical analysis of whether a numerical scheme accurately approaches the true solution as the grid is refined. Primary Methodologies If you can't find the specific book you're
: Unlike older texts, Jain’s methods are derived specifically with high-speed digital computers in mind, making them practical for modern simulations. making them practical for modern simulations.
