Error in the for loop of my function

I am trying to plot the given function :

clear all
clc
syms z 
syms s1 s2 m1 m2 j1 j2
w = 0.02;
M=1;
b=0.1;
z=linspace(-0.1,0.1);
for m1=0:M
    for m2=0:M
        for s1=0:m1/2
            for j1=0:m1-2*s1
                for s2=0:(M-m1)/2
                    for j2=0:M-m1-2*s2
                        A1=symsum(factorial(M)/(factorial(m1)*factorial(M-m1))*(1i)^(M-m1),m1,0,M);
                        A2=symsum(factorial(M)/(factorial(m2)*factorial(M-m2))*(-1i)^(M-m2),m2,0,M);
                        A3=symsum(((-1)^(s1)*factorial(m1))/(factorial(s1)*factorial(m1-2*s1))*(2*1i)^(m1-2*s1),s1,0,m1/2);
                        A4=symsum((1/(2*1i))^(m2+j1),j1,0,m1-2*s1)*(exp(2*b*z))*hermiteH(m2+j2,(1+(1i*b/2*w)));
                        A5=symsum(((-1)^(s2)*factorial(M-m1))/(factorial(s2)*factorial(M-m1-2*s2)*(2*1i)^(M-m1-2*s2)),s2,0,(M-m1)/2);
                        A6=symsum((1/(2*1i))^(M-m2+j2),j2,0,M-m1-2*s2)*(exp(2*b*z))*hermiteH(M-m2+j2,(1-(1i*b/2*w)));
                        W=A1*A2*A3*A4*A5*A6
                    end
                end
            end
        end
    end
end

Answer 1

[Walter Roberson]

The second parameter to symsum must be a scalar symbolic variable that will be summed over. However in your code, the second parameter is a numeric variable (assigned by your for loops)

It looks to me as if none of those for loops should be present.

Answer 2

[Sai Charan Sampara]

You seem to have used both a for loop and symsum function. The symsum function already runs a loop based on the index and range given as inputs.The first input of symsum must be a function of a variable(syms data type). Refer to the following link for more details on the symsum function:
