Would you please explain when this works
>> d = [1, 2, 3; 4, 5, 6];
f = size(d)
f =
2 3
>> [rows,cols] = size(d)
Why is it that this does not work?
>> [rows, cols]=[2 3]
Too many output arguments
Thank you.

The operation [2,3] is a matrix concatenation, which has only 1 output (the concatenated matrix). It is equivalent to making the following function call,
horzcat(2,3)
This is what you want to do instead,
[row,col]=deal(2,3)

"I have three different basic matlab books with the pages about 300,400, and 700 respectively but unfortunately they don't cover functions I encounter in matlab forums. They don't also cover horzcat and dial. "
This is the best place to learn MATLAB:
That page links to tutorials you can work through yourself, and the MATLAB Onramp is a series of videos that teaches basic concepts that you will need to know. Don't waste your time with out-of-date, half-baked, flawed books.

Thank you for your all introducing functions horzcat and the concept matrix concatenation.
You're welcome. If this resolves your question, though, please Accept-click the answer.
