Have you ever wanted to create a pushbutton uicontrol containing a Greek letter, some other mathematical expression or even just a multi-line label? This function will do it for you. It is very easy to use as it accepts all the same arguments as uicontrol with the addition of the Interpreter property which you can set to 'tex' or 'latex' and the Rotation property to set the angle of rotation of the text. Also, you can pass in a cell array of strings for the String property to get a multi-line label. For example,

uibutton('String','Set \beta','Interpreter','tex')

Can also create something that looks like a text uicontrol.
