continue - Pass control to next iteration of for or while loop - MATLAB (original) (raw)
Main Content
Pass control to next iteration of for or while loop
Syntax
Description
continue passes control to the next iteration of a for or while loop. It skips any remaining statements in the body of the loop for the current iteration. The program continues execution from the next iteration.
continue applies only to the body of the loop where it is called. In nested loops, continue skips remaining statements only in the body of the loop in which it occurs.
Examples
Selectively Display Values in Loop
Display the multiples of 7 from 1 through 50. If a number is not divisible by 7, use continue to skip the disp statement and pass control to the next iteration of the for loop.
for n = 1:50 if mod(n,7) continue end disp(['Divisible by 7: ' num2str(n)]) end
Divisible by 7: 7 Divisible by 7: 14 Divisible by 7: 21 Divisible by 7: 28 Divisible by 7: 35 Divisible by 7: 42 Divisible by 7: 49
Skip to Next Loop Iteration
Count the number of lines of code in the file magic.m. Skip blank lines and comments using a continue statement. continue skips the remaining instructions in the while loop and begins the next iteration.
fid = fopen('magic.m','r'); count = 0; while ~feof(fid) line = fgetl(fid); if isempty(line) || strncmp(line,'%',1) || ~ischar(line) continue end count = count + 1; end count
Tips
- The
continuestatement skips the rest of the instructions in afororwhileloop and begins the next iteration. To exit the loop completely, use abreakstatement. continueis not defined outside afororwhileloop. To exit a function, usereturn.
