disp gives wrong format

I was making a program to calculate the vertical displacement and then display a matrix of the time and displacement outputs. The output should be in seconds and meters, but disp() is changing the decimal place when the values are printed. Why is this happening? Here is the code:

% Program that calculates vertical motion under gravity - ignoring air
% friction

% Initialize Constants
g = 9.81; % gravity acceleration - m/s^2
u = 60; % initial velocity - m/s

t = 0 : 0.01 : 12.3; % time array from 0 to 12.3 seconds in 0.01 second intervals

s = u*t - g/2*t.^2; % vertical displacement equation - meters

disp([t',s']);

plot(t,s,'k','linewidth',3);
title('Vertical Motion Under Gravity');
xlabel('Time (seconds)');
ylabel('Vertical Displacement (meters)');
grid

I was not able to recreate the issue that you described. One thing to note is depending on your settings it could be outputing a scientific notation form with a call of 1.0e-01 at the start that may be confusing.

How would I check for that setting and change it?

For 2019b it is under the view tab - > Number Display Format

Try - short fixed decimal or long fixed decimal to prevent the extra scientific notation.

I have the 2016b academic version. I put format short before disp(), and it fixed the format.

Try fprintf() instead of disp():

fprintf('%6.2f,    %9.6f\n', [t; s]);

With fprintf() you can get exactly the appearance you want.
