x=linspace(0,4,100);
y=zeros(size(x));
p=0.275;
figure
k=2.031;
for i=1:numel(x)
y(i)=(exp(-(p*(x(i)))^k));
end
axis([0 4 0 1.8])
plot(x,y,'--')
xlabel('x')
ylabel('y')
How do I calculate the corresponding x value for any given y value.

You can reverse the formula with pen and paper (and maybe some Wolfram-Aplha), interpolate with a function like interp1, or solve the equation with solve. The first method doesn't really involve Matlab, and for the latter two the documentation should be self-explanatory. Nonetheless, if you have questions, you should of course feel free to post a comment here.
