求助：关于matlab的B样条拟合函数spap2

求教：matlab中的样条工具箱的spap2采用最小二乘法拟合曲线，谁知道其数学原理和具体的推导过程么，推荐一下参考资料也行啊

<p>最好是看看帮助了，下面是帮助中的话！</p><p>&nbsp;</p><p>Algorithm</p><p><br/>spcol is called on to provide the almost block-diagonal collocation matrix , and slvblk solves the linear system (*) in the (weighted) least-squares sense, using a block QR factorization. </p><p>Gridded data are fitted, in tensor-product fashion, one variable at a time, taking advantage of the fact that a univariate weighted least-squares fit depends linearly on the values being fitted.</p>
