hi to all:
i have two condition in my problem in matlab.
(1) matlab should run the first statement when x<1 .
(2) when x reaches to x>1 or x=1 the matlab should run the second statement.
thanks from all of you

Respected sir thanks from your reply but x is not single value it is matrix.
Let me explain it to you I have four rows which I called it x if one row reaches to one or greater than one than it should go to row two and follow the same procedure till last row. Thanks

[m,n] = size(x) ;
for i = 1:m
for j = 1:n
if x(i,j) < 1
statement1
elseif x(i,j) >= 1
statement2
end
end
end
thanks you so much respected sir
this is that part of my programming which i have proble.
while m(i)<1
i=1:n-1
itn=itn+1
Rhn(1:n,i) = ((pi*rh(1:n,i).^4)/8*nuD*L).*(m(i)+(1-m(i))*M);
qhn(1:n,i)=qh(1:n,i).*Rh(1:n,i)./Rhn(1:n,i);
Vh(1:n,i) = (qhn(1:n,i))./Ah(1:n,i)
if m(i)<=0.5
delXmax = 0.1
else
delXmax = 0.07
end
deltat=min(min(delXmax./Vh))
m(i)= m(i)+Vh(1:n,i)*deltat;
end
end
i want that m should strat from 0 and run in first row or column when it reaches to 1>= 1 , than it should move to second row or column and foloow same initail condition (m>=1). once again thank you so much
i is the number of rows respected sir first i wan to do it for rows than for columns .
where i=1
it should follow the rule i+1 when m>=1.
thanks
as you know in my programming the loop will stop when m reaches to 1 or greather 1, but i want it should go for i=2 and than i=3 and so on
