convert script to function in matlab

To convert a script to a function in MATLAB, you need to follow these steps:

1. Identify the lines of code in the script that you want to convert into a function.
2. Define input arguments for the function if needed.
3. Create a new function file (.m file) by clicking on the New icon in the MATLAB Editor and selecting Function.
4. Copy the code from the script to the new function file.
5. Replace any hard-coded values with input arguments.
6. Optionally, define an output argument if the function needs to return a value.
7. Save the function file with an appropriate name.

Here is an example to convert a simple script that adds two numbers into a function:

Script (addNumbersScript.m):

main.m
x = 5;
y = 10;
z = x + y;
disp(z);
35 chars
5 lines

Converted Function (addNumbersFunction.m):

main.m
function z = addNumbersFunction(x, y)
    z = x + y;
end
57 chars
4 lines

Now, you can call the function addNumbersFunction with two input arguments and it will return the sum of the numbers:

main.m
result = addNumbersFunction(5, 10);
disp(result);
50 chars
3 lines
