Using if statement inside a function,I didn't understand why the error is coming,why I am unable to use the values of x & y inside the if loop

function O = help(~,~)
i=input('Value of i:');
j=input('Value of j:');
O = y(i,j);
function g=y(x,y)
if(x==y)
{
k = rem(x,2);
s = log2( (y - k) );
g = 2^(-s);
}
else
{
g=0;
}
end
return;
end
return;
end

There is no such thing as an "if loop". The body of an "if" is executed exactly once (or not at all), whereas a "loop" would continue executing the body until some condition was met.

Please post the error message.
Be sure not to shadow the important Matlab function help by your function. This would be a very bad idea.

Curly braces for the if-else statement are not required.

As Vishal Rane has said already: remove the curly braces in the IF-block. They are not only not required, but even an error, because curly braces create a cell array.
