MATLAB: Fzero, Operands to the || and && operators must be convertible to logical scalar values.

Question

My code is:

integral(@(x) fzero(@(y) y-x-1,[0,20]),1,10)

Here is the error I get:

Operands to the || and && operators must be convertible to logical scalar values.
Error in fzero (line 444)
while fb ~= 0 && a ~= b

My fzero function is complicited. So I just use the simple fzero function of y-x-1 to replace my function.

Any help is appreciated, thanks!

Answer 1

integral(@(x) fzero(@(y) y-x-1,[0,20]),1,10, 'arrayvalued', true)
