convert workspace name into string

MatLab

Hello


I've got some workspace data in matlab, I would like to be able to convert the workspace name to a string so I can use strcat.

So given I've got a 3D array called Rubic, when i use the following commands
namenew = strcat(Rubic, 'whatever')
namenew = imnoise(Rubic, 'speckle');

I get an error

I know it's because I'm using Rubic when it should be 'Rubic'

A quick fix that I can think of is

function name(filenameworkspace, filename)

run by typing
name(Rubic,'Rubic')


Does anyone know how I can convert the name saved in workspace to a string?


Many Thanks
