I running the following if-loop:
sigmat=24;
n=1.5;
sigmam=20;
N=200;
si=sigmat/n;
if si>=sigmam
F=N/si;
end;
But after this script is run out I can not claim a value of F in command window (F should be equal 12,5). Where did I mistake in this script?

The problem is that ‘si’ is 16 and ‘sigmam’ is 20. The if condition always evaluates to false, and the if block never executes.
Also, if you want ‘F’ to output to the Command Window, remove the semicolon at the end of the line. The presence of the semicolon suppresses Command Window output:
F=N/si

Sorry!
I got it now. I have to use opposite condition as si<=sigmam to define F.
thank you Sir!
Yours look also good :)
