If you want a different type of interpolation, you put the type you want as the 4 th parameter: vq = interp1(v,x,xq,'PCHIP'); Resulting with. vq = -1.3185 -0.8534 1.8695 The available interpolation methods are: nearest, linear,spline,pchip and cubic.

Vq = interp2 (X,Y,V,Xq,Yq) returns interpolated values of a function of two variables at specific query points using linear interpolation. The results always pass through the original sampling of the function. X and Y contain the coordinates of the sample points. V contains the corresponding function values at each sample point.

This is what I have so far: time = [1 2 3 4 5 6 7 8 9 10 11 12]; temp = [10 12 15 13 [] 16 16 18 [] 15 21 20]; points = [1 2 3 4 5 6 7 8 9 10 11 12]; y = interp1 (time,temp,points,'linear') Fortunately, Matlab has also several built-in function to interpolate values with different methods (' interp1 ', ' interp2 ', ' interp3 ', and ' interpn '). ' interp1 ' is called one dimensional interpolation because vector y depends on a single variable vector x. The calling syntax is ynew = interp1 (x, y, xnew, method) This MATLAB function returns interpolated values of a function of two variables at specific query points using linear interpolation.

This MATLAB function returns the value of the 1-D function Y at the points of column vector xi using linear interpolation. This MATLAB function spherically interpolates between q1 and q2 by the interpolation coefficient T. Additional Interpolation Methods.

• The default is linear interpolation, but there are other types available, such as: – linear – nearest – spline – cubic – etc. This program calculate approximated value of x at a certain value of t using linear interpolation. vq = interp1 (x,v,xq,method) specifies an alternative interpolation method: 'linear', 'nearest', 'next', 'previous', 'pchip', 'cubic', 'v5cubic', 'makima', or 'spline'. The default method is 'linear'. If you want a different type of interpolation, you put the type you want as the 4 th parameter: vq = interp1(v,x,xq,'PCHIP'); Resulting with.

That is because you claim to want to do linear interpolation.

The default method is 'linear'. If you want a different type of interpolation, you put the type you want as the 4 th parameter: vq = interp1(v,x,xq,'PCHIP'); Resulting with. vq = -1.3185 -0.8534 1.8695 The available interpolation methods are: nearest, linear,spline,pchip and cubic. For faster interpolation when x is equally spaced, use the methods '*linear', '*cubic', '*nearest', or '*spline'.

More generally, linear interpolation is given by. $\displaystyle w(n+\eta) = (1-\eta). where $ n Below is a Matlab function which implements linear interpolation.

This MATLAB function spherically interpolates between q1 and q2 by the interpolation coefficient T. Additional Interpolation Methods. Linear interpolation gives a simple, continuous interpolant, but it may not be appropriate for all data sets. The interp1 function  The plot: Page 4. Why spline vs. linear? A typical spline interpolation will fit a 3rd degree polynomial between each successive set of 4 points. Sometimes this ”  I would rather advise you to use the ITK toolbox which is in c++ or SimpleITK which is in python if you are more use to Matlab.
