- You can get the dimensions/ size of a matrix using size.
- You can comapre the elements using inequalitties >, <. >=, <=.
- Also you can use logical indices striaght away with out loop.
- To add you have to use +.

Hi.
I'm a beginner and I'm just starting to learn Matlab so I'm not very familiar with the code syntax right now. But I'm working on the following problem.
A = [1, 2; 4, 6]
How do you use for loop to compare all the values in A to see which ones are greater than 3 and have those added together to make D?
Thanks.

You can try what A(:) prints, in command window instead of asking a question. This will help ypu to understand yourself. Anything, you have a doubts just type in command window and see it. You can get yourself.
A(:) this will make a matrix into a single column vector.
idx gives logical indices whose values are >3.
