with x =[1:1:10];
How to define y variable?

As I posted in your earlier question,
y1 = @(b, d, x) -b .* (exp(-(2/3) .* lambertw(-3 .* (b.^3 ./ a.^2).^(1/2) .* d.^3 ./ x.^3)) .* d.^2 - x.^2) ./ x.^2
y2 = @(b, d, x) -b .* (exp(-(2/3) .* lambertw(3 .* (b.^3 ./ a.^2).^(1/2) .* d.^3 ./ x.^3)) .* d.^2 - x.^2) ./ x.^2;
Now use y1(b, d, 1:10) and y2(b, d, 1:10)
Note: you will need the Symbolic Toolbox for lambertw, but see also https://www.mathworks.com/matlabcentral/fileexchange/43419-the-lambert-w-function

Symbolic toolbox with x symbolic, and solve() . You can then matlabFunction() and pass the numeric x values in .
The y1 and y2 are there because there are two solutions.
