How can I get desired plot results from equation?

input is "initialFraction"

k(1) = initialFraction; % Fraction of liver mass remaining (N)

tStart = 0;
tEnd = 300;

n = 5;
m = 0:n;
N1 = k(1) + ((1-k(1)))./(((K)*t)*exp(m));

figure(1)
plot(t, N1, 'linewidth',2)
title('Hill Function');xlabel('Time');ylabel('Fraction of liver mass remaining');
legend('N','location','eastOutside')
set(gca,'fontsize',18,'linewidth',2); box off;

I am attempting to create a hill function that will plot from the input value up to 1 in order to represent complete liver mass reproduction. How can I change the values of "K" and "m" to create the desired visual plot?

I don't understand what you're trying to do: are you trying to make a 3D plot of your N1 values against m and K? What does t do in this case?

The easiest way is usually to write a function:

 N1 = @(m,K)(k(1) + ((1-k(1)))./(((K)*t)*exp(m)));

which takes the values you want then compute it for different combinations of your values, which is easy with meshgrid. You can then plot the values of the function evaluates at the mesh points.
