I was trying to do
a=uiopen
but it doesnt work. i want a variable to be equal to whatever i open. In this case, the file i open is a 454X1 list of doubles. Thanks

You cannot do that with uiopen. Instead use uigetfile() and an appropriate method based upon the variety of file that was selected (e.g., imread(), load(), textscan(), etc.)
[pathname,dirname] = uigetfile();
fullpath = fullfile(dirname,pathname);
fid = fopen(fullpath,'rt');
datacell = textscan(fid,'%f');
fclose(fid)
a = datacell{1};
clear fullpath fid datacell
This sample code makes no attempt to protect you from the user asking to open (say) a PDF file... but neither did your original code.
