Hi,

Here is one of the possible solutions for x having a single value:

function Y = MY_fun(x)
if x>=1 && x<10
    Y = exp(-x-1)/(log10(x)+log(x));
elseif x>=10
    Y=sin(3*x)/sqrt(3*pi);
else
    Y = x^(-exp(1)+x)+sqrt(x)*abs(x);
end
end

Your code does not ever call your function f.

function y(L)=f(x(L))

That syntax is not valid. The left side of the "=" in a function statement must be one of:

A single named plain variable with no indexing at all (including no structure references)
[] around a list of named plain variables variables with no indexing at all (including no structure references). Commas are recommended between the variable names, but spaces are also accepted. Semi-colons are not accepted
The special name varargout may be used as the left side by itself, or as the last entry in a list

The right side of the "=" in a function statement must be one of:

a single named plain variable with no indexing at all (including no structure references) that acts as the function name
function name as above followed by () with nothing in the ()
function name as above followed by () and inside the () a comma-separated list of named plain variables with no indexing at all (including no structure references).
Inside the () the special name varargin may be used as the only entry, or as the last entry in a list
Inside the () the special token ~ may be used in place of any entry, such as function f(~,x)

Your code is not valid syntax because it tries to index the output variable, and because inside the () list on the right, it uses something that is not a plain variable or ~
