This should help,
https://www.mathworks.com/matlabcentral/fileexchange/30864-3d-rotation-about-shifted-axis
It will give you the homogeneous coordinate transformation matrix, M, of the rotation. So, if the equation for the plane to be rotated in homogeneous coordinates is,
[a,b,c,d]*[x;y;z;1]=0
then the rotated equation vector for the plane will be
M\[a;b;c;d]
