gnuplot不会绘制函数sqrt(2/10)* sin((3.14/10)* x) [英] gnuplot won't draw a function sqrt(2/10)*sin((3.14/10)*x)

问题描述

Gnuplot似乎无法绘制函数:

Gnuplot won't seem to draw a function:

sqrt(2/10)*sin((3.14/10)*x)

谁能告诉我为什么.我试图在 Wolfram alpha ，并且在那里完全可以正常工作.

Could anyone tell me why. I tried to draw it in Wolfram alpha and it worked compleetely fine there.

推荐答案

2/10很有可能被计算为整数除法，并将其他所有内容归零.

Most probably the 2/10 is computed as integer division and zeros everything else out.

将其更改为:

sqrt(2.0/10.0)*sin((3.14/10.0)*x)

或者:

sqrt(0.2)*sin(0.314*x)
