Matlab Fundamentals course:Creating and Calling Functions(4/5) Modify a Function: Not enough input arguments. Error in zerofuncti​on>findcro​ssing (line 23) y = y - z;

Hello, I passed Matlab Fundamentals to 97%, but there is still one task which I can´t finalize. I added everything required and checked it also in correct solution. But there is is error:

Not enough input arguments.

Error in zerofunction>findcrossing (line 23)

y = y - z;

I don´t know what to do now? Could you help me please?

Thnak you

[John D'Errico]

Hint: is y or z a function that you have defined? From the images that you show, that would seem to be the case, where y and z are function handles.

I did it but it is not solution.

Answer 1

As far as I can tell, you have not followed the instructions. The error suggests you have done part 2 correctly, but the image shows you have not done parts 1, 3 and 4.

Follow all the instructions and then submit your solution.

You are right, it is done but same problem

[Walter Roberson]

"4. Modify the two calls to findcrossing to add y0 as an input"

You did not do that.

[Cris LaPierre]

You have also not done part 3.
