disable prints from AMPL in Matlab using API

[J C]

Hello,

When I put setUp in matlab, appear the next print:

DYNAMIC JAVA PATH

 C:\Users\\Documents\amplapi\matlab\..\lib\ampl-2.0.6.0.jar

  C:\Users\\Documents\amplapi\matlab\..\matlab\matlab-lib.jar

 matlabbridgename =

    'matlab-lib.jar'

Using native binary at C:\Users\Documents\amplapi\matlab\..\bin\ampl-2.0.6.0.dll

Using api at C:\Users\Documents\amplapi\matlab\..\lib\ampl-2.0.6.0.jar

Using wrapper at C:\Users\Documents\amplapi\matlab

Anyone know if Is it possible to disable these prints in Matlab?

Other print is generated in matlab and AMPL when the solution is found, in my case the print is:

CPLEX 12.10.0.0: outlev = 0

 mipgap = 0.0

 parallelmode=-1

 CPLEX 12.10.0.0: optimal integer solution; objective 90.33415495

200 MIP simplex iterations

0 branch-and-bound nodes

I am using in Matlab the CPLEX options as: 

ampl.eval('option solver cplex;');
ampl.eval('option cplex_options "outlev = 0 mipgap = 0.0 absmipgap = 0.0 integrality = 1e-10 parallelmode=-1";');
ampl.solve();

Anyone know if Is it possible to disable these prints in Matlab? I am using "outlev=0", this option disables a lot of prints but not the above shown.

Finally

My problem is iterative and is solved through Matlab using API. When in some iteration the solution is infeasible or unbounded or simply the problem could not be solved, error messages always appear in Matlab, although I am using a routine to try to avoid this.

stat = ampl.getValue('solve_result');
if stat ~= 'solved'
    disp('the problem can not be solved');

end   

In this case I need that if the problem can not be solved only display the "disp" (not others error messages) and continue in the next iterations.

Can anyone help me?

Instead of ampl.solve(); you can use output = ampl.getOutput('solve;'); which will store the output of the "solve;" command in a variable instead of displaying it.
