3) switch case in matlab

Program

function ret = isvowel(s)
%this function will check whether the given letter is vowel or not

%If the user by mistake enters a number then we will change it to character
%using the char function. Or else also this function will not do any
%problem

s = char(s);

switch s
    case 'a'
        ret = true;
    case 'e'
        ret = true;
    case 'i'
        ret = true;
    case 'o'
        ret = true;

Explanation

In this function first we will convert the given input to a character so that if the user by mistake enters a number then the char function will change the number to corresponding alphabet. So this will not be a problem

Now in the switch case we will compare the given input with alphabets a,e,i,o,u. If the input will match the alphabet then the function will return true. Otherwise the function will return false.

I have tried to explain in such a way that it will be easy to understand for everyone. If you cannot understand, this then please do let me know, I will make changes, so that it will be beneficial for everyone. You can contact me here: contact me
