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

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

Answer 1

[ES]

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.

1. change system name with sys

2. fitfun chng with fitfund1

please sir shown with codes changes in fuction file ?

Answer 2

[ES]

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

how to seen that output?

[Pratik Anandpara]

when write in workspace lflow1(sys) ...it is seen error

undefined function or variable

how to run this all sir ?

[Pratik Anandpara]

when run this file i want output in workspace is direct

formbus

tobus

value in output

[ES]

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)' ;
