On that line instead of the right-matrix division operator (which does matrix division):
/
you need to use the right array division operator (which works element-wise):
./
And read this to know the difference:

because you will fix that line and get exactly the same error on the following lines. When you understand the difference between matrix and array operations then you can solve this yourself.

Mister can you tell me if i am solving correctly for Y , Nu and Pu in the code, as they are dependent on the ODEs.

The Runge-Kutta method looks okay, except that you are missing the for operator. You should use [your favorite internet search engine] to find examples of Runge-Kutta implementation using MATLAB (there are lots of them). Then you can compare your work, and decide if it is okay.
