Error in inline expression

>> f=inline('8 abs(9 cos^(-1)(3 - h/3) - (3 - h) sqrt(6 h - h^2))-100','h');
% Invalid expression what is wrong

[Stephen23]

I lost count of the syntactical errors.

But the most important question is: why are you using deprecated INLINE?

Answer 1

[Torsten]

f = @(h) 8*abs(9*acos(3 - h/3) - (3 - h).*sqrt(6*h - h.^2)) - 100

or

f = @(h) 8*abs(9./cos(3 - h/3) - (3 - h).*sqrt(6*h - h.^2)) - 100

depending on what you mean by cos^(-1)
