MATLAB: How to change solver’s start and stop time in Simulink through a variable

simulinksolverstarttimestoptime

How do I change solver's start and stop time in Simulink through a variable in MATLAB? I am using this command-

set_param(ModelName,'stopTime','SimStopTime')

but I am getting an error-

>> set_param(ModelName,'stopTime','SimStopTime')

Invalid Simulink object name: DummyModel3

Where DummyModel3 is my Simulink model. Any idea how to fix this?

The Simulink ModelName must be opened when you run these lines of code. Try this

open(ModelName)
set_param(ModelName,'StopTime','SimStopTime')

set_param('ModelName', 'SimulationCommand', 'start')
set_param('ModelName', 'SimulationCommand', 'stop')
set_param('ModelName', 'SimulationCommand', 'pause') <- Pause simulation
set_param('ModelName', 'SimulationCommand', 'continue')
set_param('ModelName', 'SimulationCommand', 'update')

MATLAB: Isolate a variable

If your input is x^2 + 2 + x then you cannot isolate x to one side of an equation, as your input is not an equation.

If your input is implicitly x^2 + 2 + x = 0 then your example output of x = x^2 + 2 is incorrect: instead x = -x^2 - 2

You cannot always isolate one variable -- not unless you are willing to make some restrictions on the form of the equation.

If you have a polynomial as input, then

S = x^2+2+x;
c = sym2poly(S);
isolated_x = x * c(end-1) - S;
