Ran in:
%given data
a = 45; % Angle in degrees
P = 100; % Load in Newtons
h = 1.0; % Truss height in meters
% Calculate horizontal and vertical components of the load
P_horizontal = P * cosd(a);
P_vertical = P * sind(a);
% Calculate reactions at supports
G_x = P_horizontal;
G_y = P_vertical;
% Calculate forces in members
BC_y = G_y;
BC_x = 0;
CL_y = BC_y;
CK_y = 0;
CD_x = 0;
EF_x = 0;
EF_y = 0;
KL_x = 0;
KL_y = 0;
% Display results
fprintf('Forces in Members:\n');
Forces in Members:
fprintf('BC: %.2f N (compression)\n', BC_y);
BC: 70.71 N (compression)
fprintf('CL: %.2f N (tension)\n', CL_y);
CL: 70.71 N (tension)
fprintf('CK: Zero force member\n');
CK: Zero force member
fprintf('CD: %.2f N (tension)\n', CD_x);
CD: 0.00 N (tension)
fprintf('KL: Zero force member\n');
KL: Zero force member
fprintf('EF: Zero force member\n');
EF: Zero force member

ive tried it all still doesnt run, ive given up if you can send screenshots of code running that would be helpful

One of the moderators edited your post to format your code and run it here on MATLAB Answers. Because of that, your Question is now effectively a screen capture of the output of the code as if you had run it as a Livescript.

"can send screenshots of code running that would be helpful".
It runs fine in r2023a and r2023b (see below). Now it's your turn to attach screenshots.
