It finds values of a one-dimensional function f(x) underlying the data at intermediate points. yi = interp1q (x,Y,xi) returns the value of the 1-D function Y at the points of column vector xi using linear interpolation. The vector x specifies the coordinates of the underlying interval. The length of output yi is equal to the length of xi. For interp1q to work properly, Simple Linear Interpolation using Interp1. Learn more about interp1, interpolation, linear interpolation F = lininterp1f(X,Y,XI,Ydefault) returns the value of the 1-D function Y at the points XI using linear interpolation.

In case of time repetation like the repated 60 seconds the duplication should be deleted yi = interp1q (x,Y,xi) returns the value of the 1-D function Y at the points of column vector xi using linear interpolation. The vector x specifies the coordinates of the underlying interval. The length of output yi is equal to the length of xi. For interp1q to work properly, Linear interpolation in MATLAB is obtained with the interp1 and interp2 functions.

To clarify what lower than that of the first point in Table 6.4, which is only as an interpolation-point, but can. Starting from simple cases (linear thermal case) the problems are progressively implementation of the methodologies in simple programs such as Matlab.
