我无法弄清楚如何使用thats cindyjs脚本在2个点之间创建函数（右侧的第二个图形是点 {1} v {m_ {i}和< em> {2} v {m_ {i}）或P1 [您可以选择其中一个]，它们绑定在其他2条线t_1和t_2上，或者在空间上没有单个点。我试图弄清楚如何用矩阵来处理它，例如58_Interpolation.html，但这是我的第一次，因此我在这里向您询问解决方案。我需要对数和指数函数，例如log（x），exp（x）或该点之间的常规sin（x）+ cos（x）函数，其中起点和终点必须是直线上的2个点或第二个空间免费。哦，至少。对于所有其他民族。多数民众赞成在一个完整的功能图。如有需要，请接受:)寻求帮助
