Plotting of null surfaces and Warning: Matrix is singular to working precision.

Problem: I have the following three sets of equation which i need to plot as planes in 3D system.
I ,N and T are there variables representing the null surfaces .Now i don't have to solve them, instead i just have to plot them as planes and see their intersections. Here is the plot i am supposed to get,
My attempt: I tried to use meshgrid and surf to plot the plane but i don't understand how to proceed with the first two. The third one i tried like
[T N] = meshgrid(0:0.01:5);
This led me to a warning: Matrix is singular to working precision. I checked if somewhere the denominator vanishes but they don't.
For the second i tried:
[I N] = meshgrid(0:0.01:5);
But again this did give something but nothing like the above figure. I could be completly wrong with my attempt here, hence any guidance or a small code will be extremely helpful. The variable I, T, and N are Immune, Tumor and Normal in the above figure.
