matlab surf函數(shù)的使用
|
|
y（i，j）是一個(gè)600*3600的矩陣，已經(jīng)求解出來了，希望用surf函數(shù)，將i，j作為函數(shù)y的兩個(gè)自變量表示成圖形輸出出來，求大神相助。 這是我寫的語句： [i,j]=meshgrid(1:600,1:3600); for i=1:600 for j=1:3600 z(i,j)=y(i,j); end end surf(i,j,z) 但錯(cuò)誤很多，運(yùn)行matlab提示： ??? Error using ==> surf at 78 Data dimensions must agree. Error in ==> DEEuler at 73 surf(i,j,z) [ Last edited by lixixiao2 on 2012-10-17 at 10:36 ] |

你的矩陣維數(shù)不一致， 關(guān)于surf命令與mesh使用類似，你可以看下幫助help surf help surf SURF 3-D colored surface. SURF(X,Y,Z,C) plots the colored parametric surface defined by four matrix arguments. The view point is specified by VIEW. The axis labels are determined by the range of X, Y and Z, or by the current setting of AXIS. The color scaling is determined by the range of C, or by the current setting of CAXIS. The scaled color values are used as indices into the current COLORMAP. The shading model is set by SHADING. SURF(X,Y,Z) uses C = Z, so color is proportional to surface height. SURF(x,y,Z) and SURF(x,y,Z,C), with two vector arguments replacing the first two matrix arguments, must have length(x) = n and length(y) = m where [m,n] = size(Z). In this case, the vertices of the surface patches are the triples (x(j), y(i), Z(i,j)). Note that x corresponds to the columns of Z and y corresponds to the rows. SURF(Z) and SURF(Z,C) use x = 1:n and y = 1:m. In this case, the height, Z, is a single-valued function, defined over a geometrically rectangular grid. SURF(...,'PropertyName',PropertyValue,...) sets the value of the specified surface property. Multiple property values can be set with a single statement. SURF(AX,...) plots into AX instead of GCA. SURF returns a handle to a surface plot object. AXIS, CAXIS, COLORMAP, HOLD, SHADING and VIEW set figure, axes, and surface properties which affect the display of the surface. Backwards compatibility SURF('v6',...) creates a surface object instead of a surface plot object for compatibility with MATLAB 6.5 and earlier. See also surfc, surfl, mesh, shading.
