matlab峰值拟合

你可以使用Matlab中的`findpeaks`函数来进行峰值的拟合。`findpeaks`函数可以用于找到信号中的峰值,并返回峰值的位置和幅度。
下面是一个简单的示例代码,演示如何使用`findpeaks`函数进行峰值拟合:
```matlab
% 生成示例数据
x = linspace(0, 10, 1000);
y = sin(x) + 0.5*randn(size(x));
% 找到峰值
[peaks, locs] = findpeaks(y);
% 绘制原始数据和峰值
figure;
plot(x, y);
hold on;
plot(x(locs), peaks, 'ro');
hold off;
```
在这个示例中,首先生成了一个包含随机噪声的正弦波信号。然后使用`findpeaks`函数找到峰值的位置和幅度,并将它们绘制在原始数据上。
你可以根据自己的数据和需求进行适当的修改和拟合。希望这对你有帮助!
