interpolate two lines in matlab

To interpolate between two lines in MATLAB, you can use the interp1 function. This function interpolates a set of data points (in this case, the points along the two lines) to a new set of query points.

Here's an example of how to use interp1 to interpolate between two lines:

main.m
% Define two lines
x1 = 1:5;
y1 = [1 3 4 2 5];
x2 = 3:7;
y2 = [2 4 3 5 2];

% Create a new set of query points
xq = 1:0.1:7;

% Interpolate between the two lines to get a new set of y values
yq1 = interp1(x1, y1, xq);
yq2 = interp1(x2, y2, xq);

% Take the average of the two sets of y values to get the interpolated line
yq = (yq1 + yq2) / 2;

% Plot the original lines and the interpolated line
plot(x1, y1, 'o-', x2, y2, 'o-', xq, yq, ':');
legend('Line 1', 'Line 2', 'Interpolated Line');

Note that this example simply takes the average of the two sets of y values to get the interpolated line. Depending on your application, you may need to use a different method (such as extrapolation) to get the desired interpolation results.
