tri2grid anyone??

Hi All !

Does anyone know how to define the u function in to use in tri2grid function?

this is the formula from the product help of matlab:

uxy=tri2grid(p,t,u,x,y)

it says.. computes the function values uxy over the grid defined by the vectors x and y, from the function u with values on the triangular mesh defined by p and t.

so the question is: how can we define the function u ???

Sincerely,

Mei

Although u is called a function, it's really a vector representing the values of the function on the mesh. tri2grid is intended as a postprocessor for outputs from solvers like parabolic. Try typing
