fligntest function in matlab

To test a function in MATLAB, you can use the built-in function called assert.

Here's an example of how to test a simple function called sum_numbers that takes two arguments and returns the sum.

main.m
% Define the function to be tested
function total = sum_numbers(a, b)
    total = a + b;
end

% Test the function using assert
assert(sum_numbers(2, 3) == 5, 'Error: sum_numbers(2, 3) did not return 5');
assert(sum_numbers(-2, 3) == 1, 'Error: sum_numbers(-2, 3) did not return 1');
assert(sum_numbers(0, 0) == 0, 'Error: sum_numbers(0, 0) did not return 0');

In this example, we first define the function sum_numbers that we want to test. We then use the assert function to test that sum_numbers returns the expected result for a few different input values.

If sum_numbers returns the expected result for all of the test cases, then the code will run silently. If the function fails any of the test cases, then MATLAB will pause and display the error message that we specified in assert. This makes it easy to quickly identify where the problem is in the function.
