function y=fitfund1(x)    %for this we give two values of x(1) and x(2)
sys= xlsread('IEEEE1.xlsx');    %this is excel file
sys(x(2),7)=sys(x(2),7)-x(1);
sys                             %this updated value excel file with x(1) and x(2) 
lflow1                              % this is mfile which run with this "system' excel sheet
 end

now lflow1 is mfile which is run with that updated system excel sheet

frombus = sys(:,1)';  
tobus = sys(:,3)' ;

when run this code system is unknown for this vaue

1. dont use system in our code. system is a keyword in MATLAB intended to do something else.

2. and fitfun is a function. so the value in system is visible to its workspace only. This will not be accessible by lflow1.

So a) either make lflow1 as a function and pass 'system1' to it. or b) make fitfun to write value of 'system1' into base workspace so that lflow1 can access it as you have done now.

Solution 1: a) make lflow1 as a function and pass 'sys' to it.

.m

function y=fitfund1(x)    %for this we give two values of x(1) and x(2)
  sys= xlsread('IEEEE1.xlsx');    %this is excel file
  sys(x(2),7)=sys(x(2),7)-x(1);
  sys                             %this updated value excel file with x(1) and x(2) 
  lflow1(sys)                              % this is mfile which run with this "system' excel sheet
   end

lflow1.m

function lflow1(sys)
frombus = sys(:,1)';  
tobus = sys(:,3)' ; 
end

Please try solution 2.make fitfun to write value of 'system1' into base workspace so that lflow1 can access it as you have done now.

.m

function y=fitfund1(x)    %for this we give two values of x(1) and x(2)
  sys= xlsread('IEEEE1.xlsx');    %this is excel file
  sys(x(2),7)=sys(x(2),7)-x(1);
  sys                             %this updated value excel file with x(1) and x(2)
assignin('base', 'sys', sys) %This creates a variable with name sys in base workspace with the same value of sys calculated above
  lflow1                              % this is mfile which run with this "system' excel sheet
   end

lflow1.m [This remains as you had done originally. Since sys is now available in workspace, lflow1 can access sys, and frombus and tobus will also be available in the workspace.]

frombus = sys(:,1)';  
tobus = sys(:,3)' ;

i have one function file and m file now i give values of x(1) and x(2) in function file which update in m fille and run
