MATLAB for Engineers - Introduction to while Loops (Part 2 of 4): Updating Variables and Counters

In this video, I introduce you to updating the value of a scalar variable and using a counter variable inside of a while loop. To explain this concept, we will take a look at an example problem where we determine how long it will take to double an initial account balance based on a specified annual rate of return. First, we'll take a look at the problem statement. Then, I'll walk you through a flow chart of the problem to visualize the use of a counter variable. Finally, we'll solve the problem in MATLAB.
A while loop is a loop structure for repeating a calculation until a specified condition is met. While loops are present in most programming languages and environments.
This is Part 2 of a 4 Part Series on while Loops.
Part 1 introduces the basic structure of a while loop and demonstrates a loop pass. Link to Part 1: • MATLAB for Engineers -...
Part 3 introduces the concept of storing the value of a loop variable inside of an array using an index variable. Link to Part 3: • MATLAB for Engineers -...
Part 4 introduces the concept of combing loops and logic by nesting an if statement inside of a while loop. Link to Part 4: • MATLAB for Engineers -...
The background music in the intro and outro was written and produced by Michael J Calamas for the exclusive use of David Calamas.

Understood this concept in 2 min compared to how my professor teaches. Thank you

[@EngineeringwithDrKelseyJoy]

Love the flowchart and code visual highlighting the process! Very cool!

hello, I'm from Indonesia. and your channel is really helpful for finding a detailed explanation of Matlab. your explanation is also easy to understand, I hope you can upload again some videos related to Matlab. thank you, professor,

[@humaismuhammad55]

Your videos are fantastic and easy to understand. I am watching it a day before my exam 😂❤

[@geraldfokumla2877]

Outstanding explanation. Very easy to understand. Thanks a lot

[@sheikhaalfuqaei9161]

Great explanation, Thank you so much.

[@SpartanProfessor]

Glad it was helpful!

Thanks for your comprehensive style of delivering lectures. Even the dumbest student can understand your lectures. I am a PhD student at ITB Bandung Indonesia and am trying to implement my algorithm using recursive least squares. Could you please make a video on this subject with practical example. Most videos I have seen doesn't give comprehensive explanation and examples.

Thank you :)

Great Explanation Professor , Lets buy some beers :)

[@user-ri2kn4hy7y]

hey, amazing videos! I have a somewhat unrelated question. say I wanted the balance to display as 20122 dollars rather than in scientific notation. how would I do that? Also, I have some output in the format "0.37154A(5.438715e-01" what does that represent?

[@SpartanProfessor]

The quickest way to display the output as a currency would be to use the format bank command. Otherwise, you could use the fprintf function.

thankss

[@kevaldevkar751]

I know it is a silly question but why have you add 1 in the statements??

[@obaidrehman773]

So that at the end the value of year will tell you how much years have passed to reach that condition

[@aaronpicking4935]

Tau beta pi!

Good explanation just stop being such a robot 😭
