July 27, 2022, 08:03	interpolation for 2d data	#1
hoseinBashi New Member hosein Join Date: Jul 2022 Posts: 2 Rep Power: 0	'x','y' and 'u' are 2D matrices for the x-coordinate, y-coordinate, and velocity of each node of the below mesh (figure). and I want to interpolate for (x_q,y_q) to find u_q for an arbitrary point(q). Screenshot 2022-07-27 133131.jpg My mesh is not rectangular and "interp2" error is: "Input grid is not a valid MESHGRID". Any Ideal what can I do? Thanks.
