What does this error message mean?

I am trying to write a function that graphs 'y' as a function of 'h'. I'm trying to learn Matlab and I think I may have missed something on this code since it won't work. Any advice? I need the interval to be 40 to 400 for h.

Hi Laura,

I understand that you are new to MATLAB, please refer to the links below to help you get started on the syntaxes used in MATLAB. I see that you are trying to relate MATLAB to C/C++, please understand that the syntax is different.

Additionally, I took the liberty of changing a few syntaxes and semantics in the code to get it going. I am not sure about what is expected of the output, but it works.

function plotYonH
h=50:400;
b=h/2;
s=((b'*(h.^3))./6); % used to be b*h which is mathematically not possible unless you mean element wise multiplication as below
%s=((b.*(h.^3))/6);
y=(s/384000); % I am unsure what you meant by 384000/s as s is a matrix so, changed it to s/384000
plot(h,y);
end

I hope this helps.

Thanks,

Adithya
