计算两个角度之间的绝对差 [英] Calculating absolute differences between two angles

问题描述

我有两个角度a和b，我想计算两个角度之间的绝对差.例子

I have two angles a and b, I want to calculate the absolute difference between both angles. Examples

>> absDiffDeg(360,5)
ans = 5
>> absDiffDeg(-5,5)
ans = 10
>> absDiffDeg(5,-5)
ans = 10

推荐答案

归一化差异，由于mod(x，y)采用y的符号，因此不需要进行abs操作.

Normalize the difference, abs operation is not necessary because mod(x,y) takes the sign of y.

normDeg = mod(a-b,360);

这将是一个介于0-360之间的数字，但是我们希望最小的角度介于0-180之间.最简单的方法是

This will be a number between 0-360, but we want the smallest angle which is between 0-180. Easiest way to get this is

absDiffDeg = min(360-normDeg, normDeg);
