algorithm

• calculates components ofnormal vectors of a 3d field
• using matlab tool gradient
• note: normal3 calculates coordinates of normal vectors of values of a 3d matrix;
• use extract3 after calculation, to extract normals along flame front or any arbitrary variable
   

syntax

[xn,yn,zn]=normal3(X,Y,Z,variable)

example for input

[xn,yn,zn]=normal3(X,Y,Z,CO2);

[varisoxn,f,vert]=extract3(X,Y,Z,CO2,0.03,xn,'abs','yes');
