Hello,
How I can create an empty 0x0 sym variable? Such as x=[] x={}, expect I want to make x an empyt sym, not an empty double or cell.
Thank you, Kevin

Even with double
x=[];
y=10
a=y+x % is different from y, it gives []
a=[x y], % gives y
Now with sym
x=sym([])
syms y
a=x+y, % the result is x
a=[x y] % the result is y
