WebDec 4, 2010 · To do a linear interpolation between two variables a and b given a fraction f, I'm currently using this code: float lerp (float a, float b, float f) { return (a * (1.0 - f)) + (b * f); } I think there's probably a more efficient way of doing it. I'm using a microcontroller without an FPU, so floating point operations are done in software. WebVq = interpn (V,Xq1,Xq2,...,Xqn) assumes a default grid of sample points. The default grid consists of the points, 1,2,3,...n in each dimension. The value of n is the length of the ith dimension in V. Use this syntax when you want to conserve memory and are not concerned about the absolute distances between points.

The mathematical equation for this case is as follows: y= y 1 + (x-x 1 )⨯ (y 2 -y 1 )/ (x 2 -x 1) We need the value of y corresponding to x, which makes point B (x,y). A (x 1 ,y 1) and C (x 2 ,y 2) are the two points around B. To find the required y, type the equation above in an Excel cell.
