  • Online:2007-03-25 Published:2007-03-20

摘要: 利用MATLAB计算软件,得出了无阻尼情况下单摆运动周期的精确解,并通过图示及最小二乘原理,对文献报道的十几个单摆周期的近似解与精确解进行了比较.

关键词: 单摆, 周期, MATLAB

Abstract: Using MATLAB, period of a simple pendulum without resistances is calculated accurately. Accordingly, more than ten approximate formulae are compared with the accurate one by charts and errors calculated with least square method.

Key words: simple pendulum, period, MATLAB
