A while loop executes code inside the while block continuously until the said condition is not true. A for loop contains three parts. The first part is carried out prior to the for loop, the middle part is executed by the for loop until it is no longer true, and the final part is performed at the end of each go round of the loop.
There are a lot of convolution functions in matlab, mostly in the signal processing toolbox, so it depends on what you want to do. Matlab has extensive help files available online.
Please ask clearly what you want to do with the image and explain why a nested for-loop is necessary.
The 'break' command will stop a loop from going any further, where a 'continue' command will start the loop over at the top (or bottom) of the loop, bypassing other instructions that may be in the loop. The 'continue' command will not stop a loop, but a 'break ' command will.Note: these statements aren't commands or functions.
Although both can achieve very similar loops, the one you use for a specific loop usually comes down to whichever seems more intuitive to you. In terms of performance, one method may be slightly more efficient than the other, however there are no general rules that can be applied; you must test each case by comparing the machine code or by physically timing the loops with a high performance event timer (HPET). In my experience, the performance difference is so negligible it is not worth the effort. Background activity has a far greater impact on performance.Describing the differences between every possible loop you might create would take me a lifetime, but there are a couple of subtle differences that are worth pointing out.Infinite Loopsfor(;;){} // infinite for loops do not require a condition.while( true ){} // infinite while loops MUST have a condition.To break out of an infinite loop you must test for one or more conditions within the loop itself, and call break to exit the loop when a condition is met. You can also call continue to start the next iteration before reaching the end of the current iteration.Stepping LoopsWhen stepping through a series of values, the for() loop is usually the better choice, especially if the step must occur AFTER each iteration. Consider the following similar loops:for( int x=0; x
The while loop is the more general one because its loop condition is more flexible and can be more complicated than that of a for loop. The condition of a for loop is always the same and implicit in the construction. A for loop stops if there are no more elements in the collection to treat. For simple traversals or iterations over index ranges it is a good advice to use the for statement because it handles the iteration variable for you, so it is more secure than while where you have to handle the end of the iteration and the change of the iteration variable by yourself.
the counter variable cannot be initialized in while loop before entering into the block.
Both are programming commands. A do/while loop will execute at least once. A while loop may not execute at all.
Easy: if-else is not a loop; while, for and do-while are loops.if-else just run once, but do-while run many times.
Well 'while' goes like this: while (condition) statement 'for': for (initialize; condition; after-each-loop) statement
No difference.
You mean PL/SQL? Well, they are different things, read the manual for details.
the main difference b/w do and while loops is that do loop will run atleast once even if condition is not satisfied but while loop will not execute even once if condition is not satisfied . this is bcoz in do loop condition is checked after one execution but in while condition is prechecked.
The most important differences are: a. The while loop starts with a condition whereas the condition is the line of code in case of a do while loop b. The do while loop is guaranteed to run the loop body atleast once even if the condition is an impossible to satisfy but such a guarantee is not available with the normal while loop
loop checking is perform before cable termination..the difference between a close loop and open loop is,tha close loop has a feedback while the open loop has not.
While: If we can use while statement it will check the condition then proceed further loop statement.DoWhile: If we use dowhile, first execute loop statement then check the condition.
The difference is that pre means before and post means after in Latin so it's tested before or after. :)
the test condition will be checked first after wards the body of the loop will be excuted in while statement and the the do while statement represented the body of the loop will be executed first and then the test condition will checked next
