create a function using else and if in matlab

In MATLAB, we can create a function using if-else statements. The syntax for defining a function with if-else statements is as follows:

main.m
function [output] = functionName(input)
% Function Description
% Inputs:
% input - description of input parameter
% Outputs:
% output - description of output parameter

if (condition)
   % Code to execute if the condition is true
   output = value_if_true;
else
   % Code to execute if the condition is false
   output = value_if_false;
end

end

In the above code snippet, replace the functionName with the name you want to give your function. input and output are placeholders for your input and output variables, respectively. Replace the condition with the conditional expression you want to use. value_if_true is the value that the function will return if the condition is true. value_if_false is the value the function will return if the condition is false.

Here's an example of a MATLAB function using if-else statements:

main.m
function [result] = isPositive(n)
% This function returns true if the input number is positive, otherwise false

if (n > 0)
    result = true;
else
    result = false;
end
end

In the above example, the function isPositive() takes an input parameter n and returns true if it is greater than 0, otherwise false.
