The above shown is my code when i run it shows error like this

Apparently your version of Matlab doesn't have a vertical alignment property for uicontrol objects. What release are you using and where did you find the option?
You forgot to format your code as code. Please edit your question to make it readable.

I'm using Version R2018a

There is no VerticalAlignment property for uicontrol objects (neither in R2018a or R2021b). A center alignment is the default. For other object with such a property this is generally called middle.
There is a property HorizontalAlignment. The default value is center, so you don't need to specify it.

Why did you unaccept this answer? Why is it now incorrect?
