code for matlab.internal.math.interp2 in matlab

matlab.internal.math.interp2 is a built-in interpolation function in MATLAB. It is an internal function and it is not intended to be called directly by the user. However, the function can be accessed indirectly by using the interp2 function in MATLAB.

The interp2 function can be used to perform two-dimensional interpolation on a given set of data. It takes the following inputs:

main.m
Vq = interp2(X,Y,V,Xq,Yq)

• X and Y are the arrays that define the grid of the values in V.
• V is the array of values to interpolate.
• Xq and Yq are the arrays that define the grid of points at which to interpolate the values in V.

The output of the function is Vq, which is an array of interpolated values at the points specified by Xq and Yq.

Here is an example of how to use the interp2 function in MATLAB:

main.m
% Define the grid of X and Y values
[X,Y] = meshgrid(0:0.5:10,0:0.5:10);

% Define the function to interpolate
V = sin(X) + cos(Y);

% Define the grid of points at which to interpolate the values in V
[Xq,Yq] = meshgrid(0:0.1:10,0:0.1:10);

% Interpolate the values in V at the points specified by Xq and Yq
Vq = interp2(X,Y,V,Xq,Yq);

% Plot the results
surf(Xq,Yq,Vq)
xlabel('X')
ylabel('Y')
zlabel('V')
