diff + integral in one function?
显示 更早的评论
Hi, as a beginner in matlab I have the following problem,
is it possible to use diff and integral in one function?
I want to calculate k of the image.
It would be ok to give x a fix value.
Matlab gives me the following error: [b]First input argument must be a function handle.[/b]
Is there another syms needed?
Using a @(z) at the first part of the intregral equals : [b]Undefined function 'diff' for input arguments of type 'function_handle'.[/b]
Many Thanks in advance, Lg Franz

diff is only differentiation for symbolic expressions and symbolic functions, not for function handles. You should define y as a symbolic function.
