Debashis - the error message Too many input arguments is telling you that you are calling a function and trying to pass it more input parameters than it is expecting. Look at the signature for PT
function [F] = PT(m_cp, p_cp, m_o, t)
There are four input parameters. Now look at how you are calling this function
l1 = PT(m_cp(m),m_di(m),m_o(m),t(m),p_cp(m));
You are passing five input parameters and so the error message makes sense.
If I map your variable names to the input parameters it would seem that the second one, m_di, does not belong (the function signature does not include an input with this name) and that the last one p_cp should be the second input. Please correct how you are calling this function and try again.
