computational mathematics books

If you ask a carpenter apprentice what tools do you need to work with, he may answer you: "I only need a hammer and a saw ". But if you ask an old carpenter or master architect, he will tell you, "I need some precise tools ". Because the problems solved by computers are all abstracted from life, their complexity is self-evident, so we need such accurate and effective tools to solve complex problems in real life. Algorithm And the data structure is Program An essential precision tool in design.

Tags: Io OS, using Ar Java for strong data sp I want to read more books in mathematics, but it is hard for beginners to know those books well. I collected them online and sorted them out based on my own experience:Start with mathematical analysis:Mathematical Analysis is the most important course in the Mathematics De

A lot of people asked me to recommend some excellent math books to layman's friends, some of whom didn't take advanced courses at university, only friends who were

We recommend two books on d3d and 3D graphics mathematics. Recently, I was asked about d3d and 3D related mathematics books in Chinese. We recommend the two. I will not write book reviews. But these two books are really good. If you buy it, you will not suffer losses. Introd

analysis. Not only did I not understand it when I was a student, but I also did not know it when I started to work on software development. This is because I have almost never encountered a time in my life or work that is associated with the profound mathematical formulas in textbooks. I can't even imagine a four-dimensional space. Why do I need to care about the law in a multidimensional space? When we really need to use relevant algorithms, a large number of off-the-shelf libraries and tool
