if I have defined a function si = @(x) 1.*(x>=0 & x<=0.5)+... -1.*(x>=0.5 & x<1)+... 0.*(x<0 | x>=1); and f(x)=@ x.*x; now as we know in spmd block you cannot define an anonymous function but you have to use a function handle.now in the spmd block I have to use si(2.^j.*x-k).so how should I pass these parameters j and k to si.(j and k are initialised in spmd block itself)

You should be able to call using the function handle inside the spmd block by passing the parameters to it. You can find the example in one of your previous MATLAB Answers link:

Are you receiving any errors when you call the anonymous function using the function handle inside the spmd block?

If one of the parameters is anonymous function, you can wrap it in a helper function as suggested in the following link:
