Change file matlab workspace name as the folder name

I would like to ask how to change the variable.mat name in my workspace adding the folder name.

For example: in my workspace I have 'POWER.mat' , and the folder name is 'Results2021'

I would like to rename 'POWER.mat' in 'POWER_Results2021'

Thanks for the attention, I am a beginner with Matlab.

" 'POWER.mat' , and the folder name is 'Results2021'"

Well, it depends on whether you have already created the .mat file by having used SAVE or whether you're just referring to the variable POWER shown in the workspace above. For the latter

folder='POWER_Results2021';                 % in variable to change or use cd to retrieve current
save(['POWER_' folder],'POWER')

Hi dpb thanks for the answer!

Sorry maybe I explained myseld in a bad way.

Let's say that folder name is 'Results2021'

And the variable in my workspace is 'POWER'

how do I save it as 'POWER_Results2021' ?
