how to write phi in matlab code

If your goal is to print the character in the command window or in a figure title/label/legend, then the given answers should work. If necessary, a quick websearch can rustle up whatever variant you want

https://www.compart.com/en/unicode/U+03D5

https://www.compart.com/en/unicode/U+03A6

Considrering the first link with the UTF16 point 0x03DF,

char(hex2dec('03D5'))
ans = 'ϕ'

If your goal is to use phi in the code (e.g. as a variable name), then no, that's not an option.

ϕ = 1234; % this is not a valid character for the code itself
Invalid text character. Check for unsupported symbol, invisible character, or pasting of non-ASCII characters.

You can simply copy the character.

display('α')
ylabel('α')

Unfortunately, MS Windows got the ability to display these characters to the command window relatively late. I am not certain when they were added.

The ability to use them in labels in that form requires R2014b or later, and requires that the interpreter for the text object be either 'none' or 'tex'. Unfortunately you cannot use these characters with interpreter 'latex'.

Thanks for the clarification Walter. I will also keep it in mind.

@Semih KALMA

You need to execute in Live Script to see the formatted characters.

would you share a screenshot of where I can find this property?

@Diaa

Assuming that you have a newer version of MATLAB:

In the case that you want to change the interpreter for an axes label:

Click on the axes label you are interested in. Then use the Figure menu item Edit -> current object properties to bring up the Property Inspector. In the Ticks section, click on the downward-pointing triangle that is below "YTickLabel" in order to show more Ticks properties. Scroll down there and you will see TickLabelInterpreter and a drop-menu there to change it

In the case that you want to change the interpreter for something written on the plot using text():

Click on the text you are interested in. Then use the Figure menu item Edit -> current object properties to bring up the Property Inspector. In the TEXT section (near the top), you will see Interpreter and a drop menu there to change it.

If you have an older version of MATLAB, the details might be different (for example it was different around 2016)
