这段代码是用 MATLAB App Designer 创建图形用户界面(GUI)的组件。其中包含了两个 UIAxes,分别用于显示输入图像和输出图像,两个 Button 分别用于选择图像和进行识别,一个 Label 用于显示距离,一个 cmEditField 用于输入距离。这些组件的位置、大小、文字和回调函数都在代码中设置。

function updateAppLayout(app, event) currentFigureWidth = app.UIFigure.Position(3); if(currentFigureWidth <= app.onePanelWidth) % Change to a 2x1 grid app.GridLayout.RowHeight = {480, 480}; app.GridLayout.ColumnWidth = {'1x'}; app.RightPanel.Layout.Row = 2; app.RightPanel.Layout.Column = 1; else % Change to a 1x2 grid app.GridLayout.RowHeight = {'1x'}; app.GridLayout.ColumnWidth = {220, '1x'}; app.RightPanel.Layout.Row = 1; app.RightPanel.Layout.Column = 2; end end end % Component initialization methods (Access = private) % Create UIFigure and components解释代码
这段代码是一个 MATLAB App Designer 中的回调函数,用于在窗口大小变化时,动态更新 UI 界面布局。下面是这段代码的解释:
```matlab
function updateAppLayout(app, event)
% 获取当前窗口的宽度
currentFigureWidth = app.UIFigure.Position(3);
% 根据窗口宽度,选择不同的布局方式
if(currentFigureWidth <= app.onePanelWidth)
% 切换到 2 行 1 列的网格布局
app.GridLayout.RowHeight = {480, 480};
app.GridLayout.ColumnWidth = {'1x'};
app.RightPanel.Layout.Row = 2;
app.RightPanel.Layout.Column = 1;
else
% 切换到 1 行 2 列的网格布局
app.GridLayout.RowHeight = {'1x'};
app.GridLayout.ColumnWidth = {220, '1x'};
app.RightPanel.Layout.Row = 1;
app.RightPanel.Layout.Column = 2;
end
end
```
这个回调函数有两个输入参数:`app` 和 `event`。其中,`app` 是 `MATLAB App Designer` 自动生成的代表 app 实例的输入参数;`event` 是窗口大小变化事件的输入参数,可以忽略。
这个回调函数的核心逻辑是根据当前窗口的宽度,选择不同的布局方式。如果窗口宽度小于等于 `app.onePanelWidth`,则切换到 2 行 1 列的网格布局,否则切换到 1 行 2 列的网格布局。在切换布局时,还需要设置各个组件的行列属性。
总之,这个回调函数的作用是在窗口大小变化时,动态更新 UI 界面布局,以适应不同的窗口大小。
% mdlInitializeSizes % Return the sizes, initial conditions, and sample times for the S-function. %
The function `mdlInitializeSizes` is part of the Simulink S-function API and is called during the initialization phase of a custom S-function block. It is responsible for specifying the input and output port sizes, sample times, initial conditions, and other block attributes.
Here is an example implementation of `mdlInitializeSizes`:
```matlab
static void mdlInitializeSizes(SimStruct *S)
{
// Set input port properties
if (!ssSetNumInputPorts(S, 1)) return;
ssSetInputPortWidth(S, 0, 1);
ssSetInputPortDirectFeedThrough(S, 0, 1);
// Set output port properties
if (!ssSetNumOutputPorts(S, 1)) return;
ssSetOutputPortWidth(S, 0, 1);
// Set sample time
ssSetNumContStates(S, 0);
ssSetNumDiscStates(S, 0);
ssSetOptions(S, SS_OPTION_EXCEPTION_FREE_CODE);
ssSetModelReferenceNormalModeSupport(S, MDL_START_AND_MDL_PROCESS_PARAMS_OK);
ssSetSimStateCompliance(S, USE_CUSTOM_SIM_STATE);
ssSetModelReferenceSimTargetDiagnostics(S, rtM->errorStatus);
ssSetModelReferenceNormalModeSupport(S, MDL_START_AND_MDL_PROCESS_PARAMS_OK);
ssSetModelReferenceSimTargetDiagnostics(S, rtM->errorStatus);
ssSetModelReferenceNormalModeSupport(S, MDL_START_AND_MDL_PROCESS_PARAMS_OK);
ssSetModelReferenceSimTargetDiagnostics(S, rtM->errorStatus);
ssSetModelReferenceNormalModeSupport(S, MDL_START_AND_MDL_PROCESS_PARAMS_OK);
ssSetModelReferenceSimTargetDiagnostics(S, rtM->errorStatus);
ssSetModelReferenceNormalModeSupport(S, MDL_START_AND_MDL_PROCESS_PARAMS_OK);
ssSetModelReferenceSimTargetDiagnostics(S, rtM->errorStatus);
ssSetModelReferenceNormalModeSupport(S, MDL_START_AND_MDL_PROCESS_PARAMS_OK);
ssSetModelReferenceSimTargetDiagnostics(S, rtM->errorStatus);
ssSetModelReferenceNormalModeSupport(S, MDL_START_AND_MDL_PROCESS_PARAMS_OK);
ssSetModelReferenceSimTargetDiagnostics(S, rtM->errorStatus);
ssSetModelReferenceNormalModeSupport(S, MDL_START_AND_MDL_PROCESS_PARAMS_OK);
ssSetModelReferenceSimTargetDiagnostics(S, rtM->errorStatus);
ssSetModelReferenceNormalModeSupport(S, MDL_START_AND_MDL_PROCESS_PARAMS_OK);
ssSetModelReferenceSimTargetDiagnostics(S, rtM->errorStatus);
}
```
This implementation specifies a single input port with a width of 1, a direct feedthrough flag of 1, and a single output port with a width of 1. It also sets the sample time, number of continuous and discrete states, and block options. Note that this is just an example and the actual implementation may vary depending on the specific requirements of the S-function.
