vq = interp1(x,v,xq) devuelve los valores interpolados de una funcion 1D en puntos de consulta especificos mediante interpolacion lineal. El vector x contiene los puntos de muestra y v contiene los valores correspondientes, v(x).El vector xq contiene las coordenadas de los puntos de consulta.. Si tiene varios conjuntos de datos muestreados en las mismas coordenadas de punto, puede pasar v
For surfaces, the Interpolant fit type uses the MATLAB scatteredInterpolant function for linear and nearest methods, and the MATLAB griddata function for cubic and biharmonic methods. The thin-plate spline method uses the tpaps function.. The type of interpolant to use depends on the characteristics of the data being fit, the required smoothness of the curve, speed considerations, post-fit

• There are some nice tools for doing 2D interpolation and spline fits (scipy.interpolate.interp2d, scipy.interpolate.griddata) • In a pinch, you can create many 1D splines to map out the multi-dimensional space • We will be sticking with 1D splines and interpolation 1D versus Multi-Dimensional 18 Natural cubic spline interpolation using MATLAB; Hermite interpolation using MATLAB; Neville interpolation using MATLAB; Newton’s Divided Difference for Numerical Interpol Fixed-point iteration Method for Solving non-linea Secant Method for Solving non-linear equations in Newton-Raphson Method for Solving non-linear equat
Interpolation • Interpolation is used to estimate data points between two known points. The most common interpolation technique is Linear Interpolation. • In MATLAB we can use the interp1()function. • The default is linear interpolation, but there are other types available, such as: – linear – nearest – spline – cubic – etc.

I wrote a cubic spline package in Mathematica a long time ago. Here is my translation of that package into Matlab. Note I haven’t looked at cubic splines in about 7 years, so I’m basing this off my own documentation. You should check everything I say.
