I want to design an experiment in Psychtoolbox in which the alphabet T is rotated to 90 degrees.
By rotated to 90 degrees, I mean that the alphabet T (vertical) should appear in such a way that the head of the T should be either in the left or right direction.
Here is the code that I made so far but I do not know how to proceed.
% Initialize Psychtoolbox
PsychDefaultSetup(2);
Screen('Preference', 'SkipSyncTests', 1); % Skip sync tests for better compatibility
% Get the screen number
screenNumber = max(Screen('Screens'));
% Open a window
[windowPtr, windowRect] = PsychImaging('OpenWindow', screenNumber, 0); % 0 is black background
% Set text parameters
textSize = 50;
textColor = [255 255 255]; % White color
fontName = 'Arial';
% Define the alphabet 'T'
alphabetT = 'T';

I’ve never used PsychToolbox, however that would be relatively straightforward in MATLAB graphics —
alphabetT = 'T';
figure
text(0.5, 0.5, alphabetT, 'FontSize',50)
set(gca, 'Visible','off')
figure
text(0.5, 0.5, alphabetT, 'FontSize',50, 'Rotation',90)
set(gca, 'Visible','off')
It might be necessaary to add an axes reference to the text call. See the documentation reference in ax for details.
EDIT — Corrected typographical errors.

It looks like you're working with embedded text.
You may find this resource helpful: https://peterscarfe.com/rotatingText.html
It contains a demo for rotating text in psychtoolbox by drawing the text to a texture and then to the screen.
