createButtonLabel

代码说明：

  buttonIcon = createButtonLabel(string,PVs,figOpt) Have you ever been frustrated by an inability to label a vertically oriented pushbutton or uicontrol with a string? This function is for you! All valid Parameter-Value pairs, INCLUDING TEXT ROTATION, are supported. Note that this function requires the Image Processing Toolbox, and that it triggers the creation of a temporary figure, which will be momentarily visible during button-label creation.
