How can I create a for loop that would create a "Planets" column on the left hand side while the gravity and distance data are also printed out relative to the planet name:

For example:

Planet gravity_data distance_data

xxxx xxxxx xxxx

My code is below: Thanks in advance...

%Free Fall

clear, clc

planet = ["Mercury", "Venus", "Earth", "Moon", "Mars", "Jupiter", "Saturn",...

"Uranus", "Neptune", "Pluto"];

gravity = [3.7, 8.87, 9.8, 1.6, 3.7, 23.12, 8.96, 8.69, 11.0, .58];

time = linspace(0,100,10);

%d = 1/2*(gravity.*time.^2)

[G, T] = meshgrid(gravity, time)

d = 1/2.*(G.*T.^2)

for i = 1:length(planet)

planet(i,:) = [G "_" num2str(i,"%.2f")];

end

Mercury 3.70

Moon 1.60
Mars 3.70
Jupiter 23.12
Saturn 8.96
Uranus 8.69
