least square approximation

基本解釋

Since the gradient of the velocity is high in the mould, the control method of simulation points is applied in the least square approximation.
由于口模內(nèi)速度變化梯度較大，采用最小二乘近似節(jié)點(diǎn)控制方法來(lái)控制近似效果。
In this paper, a method of least square approximation was introduced to predict the trend line of carrier movement. Then the yarn paths were analyzed systematically.
