Hi i am trying to load and use a workspace variable that i saved from previous program. My code is 

load LUT_ref.mat;

This loads fine but if i try to assign this variable to another variable for convenience purpose as
AA=LUT_ref;

or 

try to access an element in LUT_ref as
A=LUT_ref(:,54);

i am getting an error message as follws 
??? Undefined function or variable 'LUT_ref'.

Not sure whats wrong. Is it related to the memory issue because i got an error message in previous code saying 
'Out of memory. Type HELP MEMORY for your options'.
By the way the size of LUT_ref is 651x88689
Thanks in advance!
