基于FLUENT软件的一些常用UDF实例，比较有帮助(udf example)

Generic templates of algorithms for sparse matrixs

C语言实现Matlab中interp1和interp2中的功能。(Interp1 and interp2 in Matlab, C language the function.)

ADAM （Adaptive Moment Estimation）是另外一种自适应学习率算法，它结合动量梯度 下降法，在不同参数方向上采用不同学习率，保留前几次迭代的梯度，能够很好 的适应于稀疏数据。(ADAM (Adaptive Moment Estimation) is another adaptive learning rate algorithm, which combines momentum gradient. The descent method, which uses different learning rates in different parameter directions and retains the gradients of previous iterations, is very good. It is suitable for sparse data.)

s-波分裂参数计算，应用时间延迟方式,用于计算各向异性参数(shear-wave splitting time-delay calculation)

有限差分法的径向滑动轴承求解，可用于求解油膜厚度、油膜压力等(Radial sliding bearings for solving finite difference method can be used to solve the oil film thickness, oil pressure, etc.)

FFT快速傅立叶变换，DSP实际例子，学习的一手好资料。放进CCS仿真(FFT Fast Fourier transform, DSP practical examples)
