Question

请教Matlab关于contourc\contour3

Answer 1

contourf(X,Y,Z,n) %画n条等值线

contourf(Z,n) draws a filled contour plot of matrix Z with n contour levels. %也是画n条等值线

contourf(Z,v) draws a filled contour plot of matrix Z with contour lines at the data values specified in the monotonically increasing vector v. The number of contour levels is equal to length(v). To draw a single contour of level i, use contour(Z,[i i]). Specifying the vector v sets the LevelListMode to manual to allow user control over contour levels. See contourgroup properties for more information. %选取[i i]区域内的点，画length(v)条等值线
