About the Laboratory
Mission
Welcome to the Math-oriented Approach Laboratory (M.A.L.).
This site is a personal hobby project where the administrator explores "equations of the world," solving them using numerical methods and archiving the convergence processes and results.
Mathematics is the purest language for describing the natural world and engineering challenges. I aim to rediscover its beauty and record the process of unraveling complex problems.
Research Themes
Based on knowledge of numerical analysis from my student days, I publish information centered on the following topics:
- ・Solving Benchmark Problems
Tackling famous nonlinear equations and difficult benchmark problems using various approaches. - ・Implementation of Numerical Algorithms
Explanations and implementation experiments of algorithms used to derive solutions, such as the Homotopy method and Newton's method. - ・Utilizing Tools as Solvers
Circuit simulators like SPICE are treated here not as circuit design tools, but strictly as "excellent solvers for large systems of equations," verifying and utilizing their computational capabilities.
Profile
Dr. WataWata
Ph.D. in Engineering / Kendo Kyoshi 7th Dan
Firmware Developer / Numerical Analysis Enthusiast
I work as an embedded software (firmware) developer at a private company. In my student days, I specialized in numerical analysis and obtained a Ph.D. Currently, I apply that mathematical approach to algorithm design in my practical firmware development work.
I also have a face as a martial artist holding the rank of Kendo Kyoshi 7th Dan. The "static" nature of mathematics and the "dynamic" nature of Kendo. Though seemingly contrasting, they share an emphasis on "Logic (Riai)" and "Practice (Shuren)," forming the two wheels of my life.
At work, I create "things that move"; in my hobby, I solve "equations that don't solve." Perhaps as a reaction to fighting hardware constraints daily, I find my greatest joy in facing equations in a pure mathematical space.
Origin of "M.A.L."
Formal Name: Math-oriented Approach Laboratory
While holding the philosophy of "approaching the essence of problems with a Math-oriented approach," there is actually another meaning important to me.
The acronym "M.A.L." is taken from the name of my beloved dog, "Maru", who once supported my life.
Even when facing complex and difficult problems (equations), I want to solve them simply, with charm and persistence just like Maru. With that wish, I named this place M.A.L.
