function y=fungsi2(x)
y=exp(1)^(-2*x)*(sin(3*x));
end

Please help me friends...

y = exp(-2*x) .* sin(3*x);

Still Error running optimization Sir..

Subscripted assignment dimension mismatch.

Please post your code

I am going to guess that you need

y = exp(-2*x(1)) .* sin(3*x(2));

[titasari rahmawati]

thats work.

Thanks a lot friend...
