How to change Simulink constant block value to a constant variable?

Hello,

I'm trying to find a way to set constant value in constant block in Simulink to a constant variable. Namely, I want to set the constant value to g*c/3. g and c values are optimized by fmincon and determined.

In MATLAB, I tried to write something like

>> set_param([simfilename '/Constant2'],'Constant value',num2str(gc/3));

The constant block in Simulink has been named as "Constant2".

What I'm trying to achieve is to have this constant block output different numerical outputs according to g and c values determined by fmincon.

Thank you.

set_param([simfilename '/Constant2'],'Value', num2str(gc/3));

Thanks Kaustubha,

I actually had to put * between g and c as well. So this worked,

set_param([simfilename '/Constant2'],'Value',num2str(g*c/3));
