title: How can I plot an intersection of two figures from fimplicit3 in MATLAB?
body: <p>I asked it on mathworks as well but still no any replies there, so probalby someone around here will help me. </p>
  
  <p>I have two implicit functions of three variables. I plotted two surfaces using fimplicit3 in Matlab (it appeared with R2016b matlab). Then I want to intersect them and to visualize the result. How can I do it? Could anybody help please? </p>
  
  <p>For example</p>
  
  <pre><code>f = @(x,y,z) x.^2 - y^3 + z^2 - 4; 
  fimplicit3(f);
  grid on; hold on;
  f = @(x,y,z) x.^4 + y.^3 - 0.005.*z.^2 + 0.3.*cos(x) + exp(y) + 2.3.*exp(z);
  fimplicit3(f);
  </code></pre>
