thank you very much for your answer. when i tried to apply your algorithm on my real equation which is
0.016=(44/y)^(1/2)*x^(1/2)*exp(-(y/44)*x^(5/3))
x = 0.01:0.1:1;
y = nan(size(x));
for k=1:length(x)
xk = x(k);
y(k) = fzero(@(y)(44./y).^(1/2).*xk.^(1/2).*exp(-xk.^(5/3).*(y/44))-0.016, 0.5)
end
plot(x,y)
xlabel('x')
ylabel('y')
i get the following message:
Exiting fzero: aborting search for an interval containing a sign change

(Function value at -0.14 is -0.016+16.9576i.)
Check function or try again with a different starting value.
y =

f=@(x,y)(44./y).^(1/2).*x.^(1/2).*exp(-(y/44).*x.^(5/3))-0.016;
[x,y]=meshgrid(0:0.02:1, 0:5000);
z=f(x,y);
contour(x,y,z,[0 0]) % the plot is empty

You should NOT to change the question, either you know the simplification is representative, either you don't then don't do it, this is wasteful for volonteer to answer the wrong question.
f=@(x,y)(44./y).^(1/2).*x.^(1/2).*exp(-(y/44).*x.^(5/3))-0.016;
[x,y]=meshgrid(0:0.01:1, 0:5000);
z=f(x,y);
c=contourc(x(1,:),y(:,1),z,[0 0]);
j = 1;
xy = c;
jrm = [];
while j <= size(c,2)
jrm = [jrm, j];
j = c(2,j)+j+1;
end
xy(:,jrm) = [];
xy = sortrows(xy',1);
x = xy(:,1);
y = xy(:,2);
for k=1:length(x)
try
y(k) = fzero(@(y)f(x(k),y), y(k));
catch
y(k) = NaN;
end
