Hello, probably this is an easy answer, but I was wondering how I can call directly the 'variable' name as the title of a plot ?. Just the exact characters, for example the one showed in the red circle, it normally changes according to the .mat file. Thanks.

if the name is at the same position for every of your mat file you can call the struct field names using names=fieldnames(.) which gives you a cell array with the names. then you could call e.g. title(names{8})

Suppose for first .mat file, the field names are Height, Error, vrad.
Suppose for the second .mat file, the field names are Error, vrad, Height, specWidth.
How do you decide which field you want to be part of the title?

it will be something like where exacytly the field name is located?. However the answer privide by @Jonas is a good choise if we already know the numer of that 'location' , thank you so much guys.!
