HowarthsTransformation.m MATLAB Implementation for Solving Boundary Layer Problems
The HowarthsTransformation.m file provides a framework for solving boundary layer problems using the Howarth's Transformation. The function takes the following parameters:
y3y5_0 = HowarthsTransformation(rhofun, miufun, hw, M, Pr, Gamma, y3y5_0guess), with default values:- rhofun = @(h) h^(-1)- miufun = @(h) h^(2/3)- hw = 2- M = 0- Pr = 0.7- Gamma = 1.4- y3y5_0guess = [0.1; 2]
Example 1: y3y5_0 = HowarthsTransformation() (using only the default values);Example 2: y3y5_0 = HowarthsTransformation with custom input parameters.
For more details, please refer to the Wikipedia page on Howarth's transformation: https://en.wikipedia.org/wiki/Blasius_boundary_layer#Howarth_transformation

CPSid Data-Driven Discovery of Cyber-Physical Systems-MATLAB Source Code Implementation
This is the MATLAB source code for CPSid, which is a data-driven discovery framework for cyber-physical systems (CPS). The testing platform is Windows 10, and the code was implemented in MATLAB 2017a. For versions MATLAB 2018a and later, when using the slr function to identify transition logic, you should set the algorithm to trust-region. You can replace the code in line 103 of the function slr_learning_l1 with:
option = optimset('Gradobj', 'on', 'Hessian', 'on', 'MaxIter', WMaxIter, 'Display', WDisplay, 'Algorithm', 'trust-region');
Note that the CVX toolbox is required to run the code.
