皮尔逊相关性分析的matlab实现
皮尔逊相关系数可以通过MATLAB实现。你可以使用以下代码来计算皮尔逊相关系数:
```matlab
x = [0.6, 0.9, 0.78, 0.28, 0.44, 0.40, 0.69, 0.94, 0.45];
y = [31.46, 26.75, 32.08, 26.38, 29.75, 27.57, 28.56, 27.67, 28.18];
coeff = corrcoef(x, y);
pearson_coefficient = coeff(1, 2);
```
在MATLAB中,使用`corrcoef`函数可以计算两个数值序列的皮尔逊相关系数。以上代码将计算得到的相关系数赋值给`coeff`,然后从`coeff`中提取出皮尔逊相关系数的值,即`pearson_coefficient`。
请注意,以上代码需要在MATLAB环境中运行,并确保`x`和`y`数组的长度相等。
