addition of two variables without using functions in matlab

To perform addition of two variables in MATLAB without using any built-in functions, you can simply use the '+' operator. Here is an example:

main.m
% Declare and initialize two variables
a = 5;
b = 7;

% Perform addition
result = a + b;

% Display the result
disp(result);
125 chars
10 lines

Output:

main.m
12
3 chars
2 lines

In this example, we declared two variables a and b with the values 5 and 7 respectively. Then we used the + operator to perform addition and store the result in the variable result. Finally, we displayed the result using the disp function.

Keep in mind that using the + operator is the most straightforward way to add two variables in MATLAB, but it is still a built-in function under the hood. If you are specifically restricted from using any functions, including operators, you would have to implement addition manually using loops or other arithmetic operations.
