Interpolation estimates values between known data points. In MATLAB, linear interpolation, a basic method, computes values along a straight line between two points. It's widely used in fields like mathematics and engineering for approximating functions at intermediate points.

% Define known data points
x_known = [0, 1, 2, 3, 4]; % x values
y_known = [1, 2, 4, 6, 8]; % corresponding y values
% Define the point at which to interpolate
x_interpolate = 2.5;
% Perform linear interpolation
y_interpolated = interp1(x_known, y_known, x_interpolate, 'linear');
% Display results
fprintf('Interpolated value at x=%.1f is y=%.1f\n', x_interpolate, y_interpolated);
% Plot the known data points and interpolated point
plot(x_known, y_known, 'o', x_interpolate, y_interpolated, 'rx');
xlabel('x');
ylabel('y');
