I plotted this out and my next task is to find the area under each of the data points so I want 8 different values for the integral under each of the 8 organ curves. Any idea on how to do this? I am looking at the help site, and all they give for examples are actual funct...

Both area under the curve for time and frequency domain is 0.2 W but when I convert it to dBm area under it seems to be infinity. Does anyone have any idea?? 답변 (1개) dpb2024년 9월 22일 0 링크 번역 편집:dpb2024년 9월 22...
使用(统计和机器学习工具箱)函数perfcurve创建 ROC 曲线。蓝色实线代表 ROC 曲线。红色虚线表示对应于 50% 成功率的随机分类器。在图的标题中显示校准集的曲线下面积 (area under the curve,AUC) 度量。一个完美的分类器有一条最大 AUC 为 1 的 ROC 曲线。
Hi, I'm trying to find the area under the curve (ABC) for a part of a graph. I use the "trapz" function, but this function calculates the ABC for an entire area below the selected part of the graph. Any tips on how I can calculate only part of it (not the whole part up to...
