1 MATLAB Refresher and Simulink Introduction. You will be using MATLAB and Simulink for the ECE 4305 laboratory experiments, as well as for the course design project. This section serves as a brief refresher of MATLAB, since you have undoubtedly used it in previous courses.
If you do not specify name–value pairs as arguments with this command, Simulink ® generates name for the mask parameter with control type set to edit. Input Arguments blockName
In the Create Mask From group box, choose the Source luminance option. If you want to reverse the transparency of the mask data, mark the Invert mask data check box. Click OK. The mask layer and the selected layer are added to a new layer group. The mask layer applies to the selected layer only. The PTP internal block descriptions are for informational purposes only. You cannot use these blocks by themselves in a model. The subsystem mask controls the block parameters. Do not edit the parameters directly. The callback function can in turn use the set_param command to set mask parameters that affect the appearance and settings of other controls on the dialog box (see Create Dynamic Mask Dialog Box). Finally, you save the model or library containing the masked subsystem to complete the creation of the dynamic masked dialog box. Simulink ® enables you to create block masks. A mask is a custom user interface for a block. A mask is a custom user interface for a block. By masking a block you encapsulate the block diagram to have its own parameter dialog box with its own block description, parameter prompts, and help texts.
Should you require to modify these global settings, please see "How can I edit the mask aperture settings". All of the above is done automatically, however should you require a custom opening in the solder mask, such as placing Q1 horizontally on the PCB and require direct contact with the top copper this is done as follows.
