can you help please

I have this code (attached)

it keeps giving me error message saying:

Error using @(y)((-0.02^2)*sqrt(2*(9.81)*y))/(2*4*y-(y^2)) Too many input arguments.

The problem is in this (and similar) lines:

y1(i+1) = y1(i) + f(t(i),y1(i))*h;

You are passing your ‘f’ function 2 arguments when it only takes one.

Can you help me on how i can avoid this error

You already have ‘t’ defined as a vector, so I don’t know why you need it as input to your function, since you’re not using it there.

One possibility:

y1(i+1) = y1(i) + f(y1(i))*h;

and so with the others. That should at least run without problems (I didn’t test it). See if it improves your code.
