is 'continue' in 'c' language similar in MATLAB??

i am changing my code of c language in to matlab .but its gives infinite loop in Matlab during use 'continue' statement?

what is the problem? is there any other alternate of 'continue' statement?

Without seeing the code, we cannot guess what's going on. Please, kpreet, think twice: Do you really think that a useful answer is possible based on this level of information?

[preet]

my code is too long dear...thats why i did not paste here.

[preet]

let me know both continue statements are same in matlab and c language

[preet]

for i=istart:n

       if pnewperCube(i)<=tm

        flag=1;

        ppnewQR1=pnewQR(i);ppnewQG1=pnewQG(i);ppnewQB1=pnewQB(i);
        ppnewperR1=pnewperR(i); ppnewperG1=pnewperG(i);ppnewperB1=pnewperB(i);

 jmin=1;
    while j<=n
          if j==i 
               continue;

          end
           ppnewQR2=pnewQR(j);ppnewQG2=pnewQG(j);ppnewQB2=pnewQB(j);
dist2=abs(ppnewQR1-ppnewQR2)+abs(ppnewQG1-ppnewQG2)+abs(ppnewQB1-ppnewQB2);

if distmin>dist2

                distmin=dist2;

                jmin=j;

            end

            j=j+1;

    end  %j loop

 ppnewQR2=pnewQR(jmin);ppnewQG2=pnewQG(jmin);ppnewQB2=pnewQB(jmin);

            ppnewperR2=pnewperR(jmin);ppnewperG2=pnewperG(jmin);ppnewperB2=pnewperB(jmin);

            XrP=floor(((ppnewQR1*ppnewperR1)+(ppnewQR2*ppnewperR2))/(ppnewperR1+ppnewperR2));

            XgP=floor(((ppnewQG1*ppnewperG1)+(ppnewQG2*ppnewperG2))/(ppnewperG1+ppnewperG2));

            XbP=floor(((ppnewQB1*ppnewperB1)+(ppnewQB2*ppnewperB2))/(ppnewperB1+ppnewperB2));

. . . . .

Hi,

yes continue in MATLAB is the same as in C. However when I look at that while loop:

while j<=n
          if j==i 
               continue;
          end

this can`t even work in C. If j == i you will hit an endless loop because j never changes. Maybe you are missing to increment j before the continue statement?

[preet]

thanx for reply. but dear friedrich i already incremented j, problem is something else.

[Cedric]

No, the problem is precisely here. You increment j after the conditional statement, so your code is looping between the WHILE and the CONTINUE, without ever incrementing j. It would be the exact same in C, unless you had a j++ in either condition.
