During optimization by fmincon, I have set lower bound equal to 0. So fmincon outputs some variables with very small values like 0.00000056 which is almost equal to 0.
How can I set this value to be 0 if it goes lower than 0.01 in fmincon. Means I want precision to two places after decimal only in the output.

Hi,
Than setting the precision of the output of the fmincon, you can use the below given work around(as you want to set this only for the output).
n = 4; % number of desired decimal points
out= round(out*10^n)/10^n;
Hope this helps !

Thank you for the answer... but I want fmincon to return answer like this only... as I am using constraints like some of variables equal to 1...and there are lots of variables involved.
fmincon is returning all the variables with very small values and sum constraint satisfied. But I want significant values for some variables. If I use above code in this case...than all variables will become zero.
