Can anybody help me to convert the following MuPAD functions to MATLAB Symbolic Math?
//Peano Th and kernel
//pp - truncated power
pp:=(z,n)->piecewise([z>=0,z^n],[Otherwise,0]):
//PeanoKernel - compute Peano kernel given L, dex and var
PeanoKernel:=proc(L,d,t)
local K;
begin
K:=1/d!*eval(L(x->pp(x-t,d)));
return(K);
end_proc:
//PeanoCorr - Corollary to Peano Theorem
PeanoCorr:=proc(L,d)
local K;
begin
K:=L(x->x^(d+1));
K:=1/(d+1)!*factor(simplify(K))*(D@@(d+1))(f)(`ξ`);
return(K);
end_proc:
//PeanoKernel:=proc(L,d,t) //versiune veche
// local K,ff;
//begin
// ff:=x-->piecewise([x-t>=0,(x-t)^d],[Otherwise,0]);
// K:=1/d!*eval(L(x->ff(x)));
// return(K);
//end_proc:
//PeanoEstimation - Estimation based on Peano's theorem
PeanoEstimation:=proc(L,d,a,b)
local K;
begin
K:=PeanoKernel(L,d,t);
M[d+1]*int(abs(K),t=a..b);
end_proc:
The automatic conversion yields a lot of errors.

What about this
syms t
K = 1/factorial(d)*L( (x-t)^d );
L = integral(K*f^(d+1),a,b)

f^(d+1) means the derivative of order (d+1) of f

Have you seen this page? It recommends trying the convertMuPADNotebook function. It also points to the resource page Convert MuPAD Notebooks to MATLAB Live Scripts.
