How is that SURF makes 3D plots of 2D data? What data is suited for this? Newbie alert :)

Answer 1

MATLAB help is great.

doc surf

Quote: surf(Z) creates a three-dimensional shaded surface from the z components in matrix Z, using x = 1:n and y = 1:m, where [m,n] = size(Z).

Btw, plot does the same thing:

Y = sin(1:10);
plot(Y) % 1D data, 2D plot using the index of the data as missing dimension

hi Nuchto

you also have to ask : HOW plot make 2D representation of 1D data? i think that this is about theoretical conceptions
