lagrange interpolation MATLAB Program example: Question: Given set of values of x and y (5,12),(6,13),(9,14),(11,16) Find the value of x corresponding to y=15 using lagrange interpolation Solution: Tabular the given data: y: 12 13 14 16 x: 5 6 9 11 Applying lagrange interpolation formula, x(y)=(y-13)(y-14)(y-16)*5/(12-13)(12-14)(12-16)+ (y-12)(y-14)(y-16)*6/(13-12)(13-14)(13-16)+ (y-12)(y-13)(y-16)*9/(14-12)(14-13)(14-16)+ (y-12)(y-13)(y-14)*11/(16-12)(16-13)(16-14). By putting y=15 […]![]()
