This is a video in my MATLAB Tutorial series. This video builds on my previous introductory video on for loops. In this video, I discuss how you can store output values from all iterations of a for loop in a singly array by preallocation. I use a very simple example to explain the concept of preallocation. In the next video, we'll look at how to store output values from a for loop when we will have two variables that are changing. One variable will be held constant during a particular iteration of the for loop while the other variable takes on a range of values.
I hope this video helps in some way. If you haven't already, please SUBSCRIBE!!! Check out other videos on my channel, especially the MATLAB tutorial series as well as the graphing and scientific calculator tutorial series. You can also check out the math videos on my channel.

Wow you are my savior, It's 10:30 on a saturday because i figured taking a break was a good idea and this video, and your excellent explanations about the littlest things (which was incredibly useful because I tend to forget things) has saved my ass from this matlab assignment

Sir how can I print the each iterative value in loop.... I.e. -we have to print individually y(1)=0 y(2)=3 ...... y(11)=30 Sir please I am waiting this side....I have to use in our ph.d program

Thank you. But my issue is, I want to store output values into an array of unknown size! There seems to be no MATLAB equivalent to ".append()" where we can append values into an array without redefining the size of the array. Can anyone help me here?

same here. i have an if statement inside my for loop, so the size of the end array is generally unknown. it doesnt help im a matlab beginner...

hi, after some googling i somehow found a solution haha. so here is an example: pressure = [] %define an empty array for i=1:10 %execute the for loop for desired columns in a 2d array/matrix if T(row,i)~=0 %define a condition p=T(row,i); %what happens if the statement is true pressure=[pressure,p]; %append the p value to the empty pressure array end end
