MATLAB: Plotting Contour with point coordinates

contourinterpolationMATLAB

Trying to plot elevation of head contours given point coordinates. need direction on how to appraoch problem or how to get matlab to interpolate between different points inorder to get a contour of a given head . here is the given data points.

Best Answer

Arc-length interpolation
L = sqrt(diff(x).^2 + diff(y).^2);
t = [0 cumsum(L)];
t1 = linspace(0,t(end),50);
x1 = spline(t,x,t1);            % interpolate X data
y1 = spline(t,y,t1);            % interpolate Y data
plot(x,y,'or')
hold on
plot(x1,y1)
hold off
