Simulink is a powerful simulating and programming tool. In many applications, we need to write scripts to automate specific tasks. At this time, we often need to obtain or modify the parameter values of the block diagram in command line. get() and get_param() Simulink provides get and get_param functions to Read more…
It looks that in newer versions of Matlab, some HMI (Human Machine Interface, e.g., Diagnostic Viewer, Live Scripting) functions are realized by means of local network port communication. However, this approach seems unreliable. From year 2014 to 2020, many users reported the blank Diagnostic Viewer issue in various Matlab versions. Read more…
Simulation Data Inspector is a useful tool to view or compare the simulation results of Simulink. Compared to the Scope block, the Data Inspector is more flexible to use. However, after a period of time, the .dmr file of Data Inspector may become very large. Large .dmr file will affect Read more…
Recently I discovered an undocumented feature of Simulink, i.e., plot bold line in block mask’s icon drawing commands. Limitations of the plot in icon drawing commands The plot function in the mask is a reduced plotting function. If we specify the linewidth parameter to it, an error will be prompted: Read more…
Chinese Title: 为 Simulink Embedded Coder 增加模块中间变量的初始化功能 Transfer Function of First-Order LPF For a simulink block, the mask’s initialization commands is not included in the generated code. Take a first-order low-pass filter for example, the Laplace transfer function { Y(s) = \cfrac{\omega}{s+\omega}} In the time domain, {y_n = a \cdot Read more…
