Expected a value representable in the C type 'int'.

Hello everyone,

I am simulating a simple equation in simulink as a matlab function block. and i am getting the following error, The code is also as follows#

function dHdt = fcn(R, L, H, m_s, m_w)

dV_wdL = 2*L(sqrt(2*R*H-H^2));
dHdt = (m_w-m_s)/(dV_wdL*(997-0.592));

The error is as follows
Expected a value representable in the C type 'int'.  Found 0.489898 instead.
	Error in 'onelast/MATLAB Function2' (line 3)
		dV_wdL = 2*W(sqrt(2*R*L-L^2));
Component:Stateflow | Category:Runtime error
Index exceeds array dimensions.  Index value 0 exceeds valid range [1-1] of array L.
	Error in 'onelast/MATLAB Function2' (line 3)
		dV_wdL = 2*W(sqrt(2*R*L-L^2));
  

Please help me with this.

Thank you in advance.

Hi!

I'm having the same class of error. Were you able to solve it?

Thanks

In the code above it looks like there is a missing multiply operator. The 2*L(sqrt... should be 2*L*(sqrt(...

Similar comments for the 2*W(sqrt...

What does your code look like? Maybe you should open up a new Question.

Thanks James,

I also had the same issue and now it works.

The error Matlab shows and the solution to that problem is completely different.
