"What is the difference between + and .+ explain with example."
The difference is very simple:
- + is a MATLAB operator (shorthand for the PLUS function),
- .+ does not exist.
"Suppose i am adding two matrices which is best and what are their roles."
Using the operator that actually exists is more likely to succeed.

Theree is no ‘.+’ (or ‘.-’) operator. (Using them would throw an error.) The dot operator with multiplication (‘.*’), division (‘./’), and exponentiation (‘.^’) are element-wise (array) operators, as opposed to matrix operators. Seee the documentation section on Array vs. Matrix Operations for details. Addition and subtraction are always element-wise operations.
