===== Primitive: Convolution with mesh (set of connected triangles) =====

**Definition**: <m>sum{}{}{f(r)}</m>\\
f(x) is analytical convolution for a triangle with Cauchy kernel [McCormack and Sherstyuk 1998]\\

**Call**: hfConvMesh(x,vect,tri,S,T);

**Parameters**:

x - point coordinates

vect - coordinate array for vertices

tri - index array of vertices for triangles (3 elements each)

S - array of kernel width control parameters for each triangle

T - threshold
