What are the different interpolation methods available in MATLAB?
The most common interpolation technique is Linear Interpolation. A more exotic interpolation scheme is to link the data points using third degree or cubic polynomials. In MATLAB, we can interpolate our data using splines or Hermite interpolants on a fly.
What are some benefits of interpolation in MATLAB?
Interpolation is a technique for adding new data points within a range of a set of known data points. You can use interpolation to fill-in missing data, smooth existing data, make predictions, and more. Interpolation in MATLAB ® is divided into techniques for data points on a grid and scattered data points.
How do you perform linear interpolation in MATLAB?
The function to perform linear interpolation, MATLAB provides the interp1 () function. Here, a sample point is a set of data points, which could be an array or a vector. The value of the unknown function on sample points is also a set that has the same size/length as the sample points.
