turn script into function in matlab

You can turn a script into a function in MATLAB by following these steps:

1. Copy all the code from the script to create a new function.
2. Add the function declaration line at the beginning of your code. The function declaration line consists of the keyword function, followed by the output variables in square brackets (if any), the function name, and the input variables in parentheses.
3. Replace any hard-coded inputs in your script with the input variables of the function.
4. If your script contains any output variables, make sure to assign values to them within the function.
5. Save the file with a .m extension and call the function from another script or the command window using its function name.

Here is an example to illustrate the transformation from a script to a function:

Script (original code):

main.m
% Script to calculate the area of a rectangle

length = 5;
width = 3;

area = length * width;

disp(area);
107 chars
9 lines

Function (after transformation):

main.m
function area = calculateRectangleArea(length, width)
% Function to calculate the area of a rectangle

area = length * width;

disp(area);
end
143 chars
8 lines

Then, you can call the function calculateRectangleArea in MATLAB with the appropriate inputs:

main.m
area = calculateRectangleArea(5, 3);  % Output: 15
51 chars
2 lines
