MATLAB: Return to a previous statement

loop

Guys,in my code I have assigned some values to certain variables and then I did some analysis.The results of analysis, are then checked for some conditions.When the condition is not met, the values will have to be re assigned.My confusion is ,how to go back to the line where values have to be assigned. eg
a=value1 ;b=value2;
%analysis
  if (condition)
    % code
else %go back to the statement where new values will be assigned i.e at beginning
  end

Best Answer

while( true )
    a = value1; b = value2;
    % analysis
    if( condition )
        % code
        break
    end
end
If the condition is met, the code will break out of the while loop.
If the condition is not met, the code will automatically loop back to the beginning of the while loop.
Note: This loop construct is typically known as a DO-UNTIL loop.
