how to use two while and for loops?

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

if x < 1
    statement1
elseif x >= 1
    statement2
end

Respected sir thanks from your reply but x is not single value it is matrix.

[Engineer Batoor khan mummand]

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

[Engineer Batoor khan mummand]

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
