WebBoth polyfit and corrcoef are order N algorithms so both run very fast. Legendre and Gauss performed fitting by hand circa 1800. You can run polyfit and corrcoef one right after the other. If you don't want to use corrcoef you have to do a little extra work to get the output structure of polyfit to a correlation coefficient. Webpolyfit函数是matlab中用于进行曲线拟合的一个函数。其数学基础是最小二乘法曲线拟合原理。曲线拟合：已知离散点上的数据集，即已知在点集上的函数值，构造一个解析函数（其图形为一曲线）使在原离散点上尽可能接近给定的值。 bivins fcu
