i have a condition for my code

stage A

A1= Zmed-Zmin

A2=Zmed-Zmax

if A1 >0 and A2 <0 go to stage B

else w=w+1

if w < wmax ,repeat stage A

else output zmed

stage B

B1= Zxy -Zmin

B2 = Zxy - Zmax

if B1>0 and B2<0 Output Zxy

else output Zmed

can someone help me in for this code

i tried writing it as

while 1

A1=Zmed-Zmin

A2=Zmed-Zmax

if A1>0 && A2<0 break

else w=w+1;

if w <= Wmax continue

else

B(i,j)=Zmed;

end

B1=Zxy-Zmin

B2=Zxy-Zmin

if B1>0 && B2<0

B(i,j)=Zxy;

else

B(i,j)=Zmed;

end

but its not working

Try continue instead of break

asim asrar 2019-11-2

but i have the condition that if A>0 and A2<0

then i have to come out of the loop

so i have to use brak for that ,

my question is how to code this conditions -

stage A

A1= Zmed-Zmin

A2=Zmed-Zmax

if A1 >0 and A2 <0 go to stage B

else w=w+1

if w < wmax ,repeat stage A

else output zmed

stage B

B1= Zxy -Zmin

B2 = Zxy - Zmax

if B1>0 and B2<0 Output Zxy

else output Zmed
