Here is my code:
function [Height,Range] = catapult(InitialV)
% calculates at Angle 30 degrees
Angle = 30;
fprintf('For an Angle = 30 Degrees\n')
for v = InitialV:10
% Used to find Velocity in Y direction
Vyinitial = (v * sind(Angle));
% Used to find the total time
Tfinal = ((2*v * sind(Angle))/9.8);
% Used to find time for maximum height
Time = Tfinal/2;
% Used to find max height
Height = Vyinitial * Time - (.5 * 9.8 * Time^2);
% Use to find velocity in x direction
Vxinitial = (v * cosd(Angle));
% Used to find total distance
Range = Vxinitial * Tfinal;
fprintf('%3.2f %6.2f\n', Height,Range)
end
%calculates at angle 35 degrees
Angle = 35;
fprintf('For an Angle = 35 Degrees\n')
for v = InitialV:10
% Used to find Velocity in Y direction
Vyinitial = (v * sind(Angle));
% Used to find the total time
Tfinal = ((2*v * sind(Angle))/9.8);
% Used to find time for maximum height
Time = Tfinal/2;
% Used to find max height
Height = Vyinitial * Time - (.5 * 9.8 * Time^2);
% Use to find velocity in x direction
Vxinitial = (v * cosd(Angle));
% Used to find total distance
Range = Vxinitial * Tfinal;
fprintf('%3.2f %6.2f\n', Height,Range)
end
%calculates at angle 45 degrees
Angle = 45;
fprintf('For an Angle = 45 Degrees\n')
for v = InitialV:10
% Used to find Velocity in Y direction
Vyinitial = (v * sind(Angle));
% Used to find the total time
Tfinal = ((2*v * sind(Angle))/9.8);
% Used to find time for maximum height
Time = Tfinal/2;
% Used to find max height
Height = Vyinitial * Time - (.5 * 9.8 * Time^2);
% Use to find velocity in x direction
Vxinitial = (v * cosd(Angle));
% Used to find total distance
Range = Vxinitial * Tfinal;
fprintf('%3.2f %6.2f\n', Height,Range)
end
end
My question is I would like to have the same loop be able to go through the three different angles listed and then also go through the "InitialV" input variable to 10. I would also like it to output a matrices like table where it has the 3 different angles listed in a column and then the different 'V' velocity in a top row and then the data in the table would be the different Heights and Ranges in the matrices table. Pic of table.

You can make an array with the 3 different angles and run a nested for loop then store the values in a table.
So your code would look something like:
function out = catapult(InitialV)
Angles=[30 35 45];
out=table();
for a=1:3
Angle=Angles(a);
temp=table();
for v = InitialV:10
% Calculate Height and Range using the same formulae
temp.(['velocity_' num2str(v)])=[Height,Range];
temp.Properties.RowNames=cellstr(num2str(Angle));
end
%Now add this row to the output table;
out=[out;temp];
end
end
This will return a Table Where each entry in the table is two values Height and Range
If initialV=8 then the output would look like
out =
3×3 table
velocity_8 velocity_9 velocity_10

I love it! So is table() a method then? Also what does temp. do? Also could you possibly give me a breakdown of what each part of the code is doing at these two lines:
temp.(['velocity_' num2str(v)])=[Height,Range];
temp.Properties.RowNames=cellstr(num2str(Angle));
Like what is Properties. and I'm assuming num2str is a method to take a number and make it a String text? Also lastly why did you do:
Angles=Angles(a)
What does that mean and do exactly? I apologize if this is asking a lot! I understand if you don't want to hassle with responding!
Thanks either way for the answer.
