Hi I'm really new to MATLAB. My questions is how to a start a new line without executing the code. For example if I have:
y = 1123414124124124124 (want new line here without executing)

Are you typing your code in the Command Window? Then use "..." and < enter >
But I suggest you start typing your code in a script. (Home > New > Script)

I have an incredibly long piece of code that only calculates one thing (in the worst way possible). I'm just trying to format it nicer. Thank you I will try out script and see if it helps.

Note that in modern versions of MATLAB, the "..." operator has an implied seperator before it.
In sufficiently old versions of MATLAB,
[123....
456]
would have been treated as 123.456. In modern versions of MATLAB, it is treated the same as
[123. ...
456]
and so would result in [123. 456]
Side note: the parsing of literal constants takes priority over the ... operator. Entering
[123...
456]
is treated as "123." followed by ".." which is a syntax error.
But
A = 123;
[A...
456]
would be treated as [A 456] which would be [123 456]

add ";" at the end, then click enter

Ran in:
That will end the current command (or end the current row, if it appears inside square brackets or curly braces to create a matrix or cell array.)
x = 12345; % This is one statement
y = [1 2; % This ends the first row of matrix y
3 4]
y = 2×2
1 2 3 4
<mw-icon class=""></mw-icon>
<mw-icon class=""></mw-icon>
z = {'apple'; % This ends the first row of cell array z
'banana'}
z = 2x1 cell array
{'apple' } {'banana'}
If you want to continue the command on the next line, using ... is probably the right thing to do.
q = 12345 + ... % Continue the statement on the next line
67890 % These two lines are the equivalent of "q = 12345 + 67890"
q = 80235
See this documentation page for more information on using ... and/or ; in MATLAB.
