Is it possible to display values to only one decimal place?
Thanks
Edit: I'm trying to do it for a UI table

Use sprintf
sprintf('%1.1f',pi)

If you are referring to %10.1f as suggested by Oleg, then a difficulty with it is it is an attempt to create aligned columns, but uitable usually default to proportional spaced fonts that are not going to line up.
Using %10.1f could potentially look okay if you forced the font to be one of the monospaced fonts.
Note: when you use sprintf() to format values for uitable, you would save the result of sprintf() into a cell array of character vectors, and that cell array would be the Data that you would set for the uitable. The resulting entry would be character, not numeric, so if you permit editing of the column the user could easily put in non-numbers and whatever they enter is not going to be automatically aligned (or have its display rounded to the desired number of decimal places.)

Not without overriding the display() method. In particular, it is not possible to do this using the format() command.
If you have special formatting requirements it is usually best to use fprintf() or sprintf()

Sorry, uitable cannot specify the number of decimal places. The closest you can get to that is to specify "bank" format for the column, which would get you two decimal places.
To display data to one decimal place in a uitable, create the table column as char and write pre-formatted strings in to the cells.
