For example,
I have a point set( A), where each point corresponds to a value of (Value_A). We can use "scatteredInterpolant" function to obtain the value (Value_B) on a point set B. However, this process is very time-consuming for a large number of points.
In my code, this interpolation process is required frequent operations, but the point sets A and B do not change, only the value (value_A) on the points will change.
In this case, can we extract the weight matrix A2B from A to B and directly obtain (Value_B) through Value_A * A2B. This way, the overall efficiency will be very high. I tried to check the underlying code of the scatteredInterpolant function, but it was not available.For example,
