Usage
P_interp = interp_with_shapefnc(N, P, MSH, opt)
Input
N: [1 x N_sh] Shape functions values. This is the outcome of the functions shapefunctions.m
P : [Np x 1] The property for interpolation defined on the nodes. Np is the number of nodes in the mesh
opt : a structure variable with fields:
dim: dimension of the elements e.g. 1, 2 or 3
el_type: type of elements
el_order: order of elements
Output
P_interp: interpolated values on the points defined by the shape function values
