# MATLAB: The problem of using ‘case’

MATLAB

i want to use a loop of omega and when the omega has diffreent value ,the m0,m1,m2…have the different value,so in the loop i use the 'case' as this
``for omega=0.1:0.1:2;  switch omegacase 0.100000;m0=0.031949;m1=3.141268;m2=6.283023;m3=9.424670;m4=12.566289;m5=15.707898;m6=18.849502;m7=21.991102;m8=25.132701;m9=28.274298;m10=31.415894;case 0.200000;m0=0.063931;m1=3.140293;m2=6.282536;m3=9.424345;m4=12.566046;m5=15.707703;m6=18.849339;m7=21.990963;m8=25.132579;m9=28.274190;m10=31.415797;``
and there are still some codes,but in the result,when omega=0.2,it still use the m0,m1,m2…of case 0.100000;
so when i change it as
``case abs(omega-0.200000)<0.01;``
it still has the problem,and why,thanks a lot!!!

``for omega = 0.1:0.1:2;	switch omega	case 0.1		disp('one')	case 0.2		disp('two')	endend``

``for omega = 0.1:0.1:2;	switch true % this is the value for a valid CASE.	case abs(omega-0.1)<0.01;		disp('one')	case abs(omega-0.2)<0.01;		disp('two')	endend``
