i want to plot a graph with Y-axis Ek (named Kinetic energy) and X-axis (Time). and i need to plot every t value in one graph. every t value (0.6 0.74 ... ) needs to be ploted as a point in the graph. please help me out.

m = 100; L = 1; a = 0.0058;
J = (m*L^2)/3+(m*a^2)/12    %value for equasion.
t = [0.6 0.74 0.86 0.98 1.2 1.37 1.58 1.87]     %time points from sample.
w = pi/(2*t)     
Ek = J*w^2/2;        %kinetic energy.

在 MATLAB Online 中打开

but how do i do for this:

p1 = 101325;
h1 = 53.19;
h2 = linspace(52.19, 8.94, 10)
g = 5/3;
slag = h1-h2
p2 = p1 * (h1/h2)^g

h2 has to be from 52.19 to 8.94, and i need to put in into the funktion and i want to get 10 values for p2 for every h2 then plot it into a graph with y-axis p2 and x-axis s and a title "Tryck i funktion av slaglängd".

Would be thankfull for the help!
