MATLAB: What happens if output and input parameters are given same name

Question

Can input and output parameters of a function share same name? Example:

function a = functionName(a , b)
% code
end

What sort of conflicts would occur in such case? Please care to explain.

Thanks.

Answer 1

Nothing will happen only the values of the variable will be changed

inputVal = 10;

inputVal = rand(inputVal)

now the value of the 10 will be replace by 10 * 10 matrix value
