QM 自學你有排玩

如果冇background 我諗最少要1個sem fulltime時間你先會入到門

做Analytical 好難唔用Mathematica 幫手
除非你把炮到背左成本Gradshteyn & Ryzhik

Symbolic computation
MATLAB唔係冇，但係差好多
其實最好唔好當Mathematica係programming language

有excat solution邊個會想做simulation

唔止Physics係咁，你做statistics 都係咁

好多asymptotic 既野sum 唔到

我本身都唔係做stat，係consumer啫

i mean本身唔係做緊formal science research嘅話，正常唔係應該有standard嘅closed form solution（eg (X^TX)^(-1)X^TY）就closed form，冇就numerically 搞掂算咩 numerical method主要係computational power問題姐，但係而家強啲嘅電腦唔係難搵，點解唔盡量俾個電腦搞掂晒

冇學過summation嘅na 可唔可以講下有咩情況下係sum唔到？
