4 d相当于3 d曲面拟合怎么办?

我有三个独立参数和1相关的参数。我想找到一个方程的最适合的数据。类似于 曲线拟合 但这需要4 varriables。

例如,

Y = [3, 9, 2、3、3、1 0 4, 3、4、2、3, 3, 5, 5、2、6、5、2、7、4、4、3、4、8);

= ( 59.76169,48.94491,109.2504,41.13384,119.1513,128.789,72.16298 ,134.1063 ,103.9212,151.3553,114.1976,105.0117,87.97976,85.17248,157.5749,144.1309,102.5106,118.2031 ,90.04979,73.26943,51.56135,113.2476,90.25419,52.70711,65.29004);

b = ( 34.03245,62.00777,65.26073,35.14924,60.43905,13.2536,81.35409,42.96087,20.11143,51.95549,48.69367,103.4722,86.34748,36.3594,34.22509,29.06005,66.28552,50.34202,68.52923,13.37169,79.57046,16.90741,19.23409,10.61589,56.88702);

c = ( 162.0816,79.415,83.82825,27.93687,40.62826,82.24879,138.5984, 90.97681, 99.80004, 67.54529, 94.40013, 122.3847, 111.1037,73.3585, 97.30746, 122.7819, 173.2984, 123.2553, 70.9507, 124.8281, 109.5493,107.5167, 104.1119, 100.0313, 98.01023);

如何让一个方程或模型,可以给一个输入输出Y, b, c ?
