MATLAB Plot- URGENT. I am trying to plot for a variable incrementing 1:K for a specified value K. The variable in question is P, which is to by my y-axis. The plot itself is an attempt at modeling a JKR/Hertzian contact mechanics curve for a given specimen I have used. I have written all the constants and provided the equations as they are in the MATLAB code I have written. There are several problems: . The plot won't graph. It will open up the window and no curve or point is plotted.

. The workspace shows incorrect values for constants a0R1 and a0R2, including other constants. If you calculate them by hand using the variables I have provided, you will see what I mean.

. The values in the workspace seem to be overwriting each other so I don't know how to plot JKR_Total for a continuous stream of varying P, by increments of deltaP = 0.4e-8. The code is attached as two pictures below:
