What is your octave version? Hi, I have experiment the contour function again yesterday, and if the code as following is wrong, always rise many level lines. the code(the u matrix is u matrix): figure, contour(u, [0 0]). However, If I modify the code as following , the result is good. the modified code: [nrow ncol] = size(u); figure, contour(1:ncol, 1:row, u, [0 0]) As description by the manual, it should be same whatever the x and y be transfered to contour function, that's why ? zzpwelkin |
