MATLAB: Evaluate expression

asymptoteevaluateMATLABplot

      I have equation y=x*exp( (1-y)/(A*y)*B ) where A nd B constants in my program. I have a vector values for x. How can I evaluate y to plot y versus x ?

Best Answer

ezplot(['y-x*exp( (1-y)/(' num2str(A) '*y)*' num2str(B) ')'],[x(1) x(end)])

 As = ...; 
 Bs = ...;
 y = zeros(size(x));
 for j = 1:length(x)
    y(j) = fzero(@(y)y-x(j).*exp( (1-y)./(As*y)*Bs ),1);
 end
 plot(x,y);
