How do you do interpolation in mathlab?

In MATLAB, you can perform interpolation using functions like interp1, interp2, or interp3 for one-dimensional, two-dimensional, and three-dimensional data, respectively. For example, to interpolate a set of points, you can use interp1(x, y, xq) where x is the original data points, y is the corresponding values, and xq is the query points where you want to estimate values. You can also specify the interpolation method, such as 'linear', 'spline', or 'nearest'. For higher dimensions, use interp2 or interp3 similarly by providing the grid and values.
