I have my code where DDD is a 35x60 matrix I'm trying to get integer values for w(26:60) but its giving me

For my Code:

intcon= zeros(35,1);
for i= 1 : 35
   intcon(i,1)=25+i; 
end
D = [ DDD ; eye(25), zeros(25,35); -eye(25), zeros(25,35) ] ;
f= [zeros(25,1) ; g ; -1 ]  ;
b=[zeros(34,1); [1-0.0001 ] ; ones(25,1); ones(25,1) ] ;
w = intlinprog(-f,intcon,D,b) ;

Writing this just for future users: The intcon code you are using seems to be wrong. Intcon should be (1,35) for your problem. So all numbers should in the first row. The following code could solve this problem. As Matt mentioned, ub and lb are also necessary for particular bounds on variables.

intcon = 26:1:60;
