Using the operator @ and the function

Dear all,

I have a function

function ll=sample(x,a,b,c,d)
    
end

, where x appears in 1000 equations in various positions.

I am using an algorithm that works as follows for a simple function LL

LL=@(x)   x.^2 ;
[output]=Algorith(LL,xz,e,r);

How can I adjust my function ''ll' so that I can use this algorithm?

Many thanks

Could you be more clear?

I did not get exactly what you are asking.

Thank you.

I have a 500 by one vector. Each element of this vector appears in 1000 equations.

I want to update each of these elements, one at a time. Each time, the element which should be updated is my 'x'

To this end, I found a function from an author to do that but it has the above simple template;see the LL example, where 'x' appears in a single equation

However, in my case 'x' appears in thousands of equations.

I want to tell the ALGORITH that I want to update x that belongs to thousands of equation?

But I use 'function', whereas the ALGORITHM uses the operator @

Your second example can equivalently be written as

output = Algorith(@sample,xz,e,r)

function LL = sample(x)
  LL = x.^2;
end

Can you take it from here ?
