MATLAB: Am I unable to use “feature(‘​uselinesea​rchsolver’​,1)” with Simulink 6.5 (R2006b)

Question

When I execute the following code:

feature('uselinesearchsolver',1)

I get the following error message:

 ??? Error using ==> feature
 An unknown feature was specified

This command works fine in R13SP1 and R2007b.

Answer 1

The behavior observed is because Simulink was not loaded. To work around the issue, load Simulink first and then issue the command. For example, you can use the following code:

simulink
feature('UseLineSearchSolver',1);

or execute:

slfeature('UseLineSearchSolver',1);
