Specify optional 'Visible' and a numeric or logical This is the intended behavior. 最新のリリースでは、このページがまだ翻訳されていません。 このページの最新版は英語でご覧になれます。, campos rigid3d object. pair arguments in any order as 僕は研究の都合上,一度の実験で30個ほどのデータをグラフ化しなければならなかったりします. 以前までは単純なグラフ作成のコードを使って一つのグラフを作成する度に実行を押し,保存をするという途方のない作業(今思えばめちゃくちゃバカらしい)を行っていたのですが,作業効率化のために一度の実行で複数のグラフを作成・保存できるようにしました. 似たような記事もあるかもしれないですが,そのときのコードをメモとして残しておきます. campos('auto') Principal axes constrain camera-tool motion along axes that are (on the screen) parallel and perpendicular to the principal axis that you select. cam = plotCamera plots a default Specify the position as a three-element vector containing the x -, y -, and z -coordinates of the desired location in the data units of the axes. 1 (true) or campos returns the camera position in the current axes. Expand the viewable limits of each axis. You clicked a link that corresponds to this MATLAB command: Run the command by entering it in the MATLAB Command Window. campan Rotate camera target around camera position camzoom Zoom in and out on scene camdolly Move camera position and target camlookat Position camera to view object or group of 1.2 described in the Matlab help, so there is a lot of usefulness in the knowing this command. Compute the camera location and orientation. Each column title must match the name-part of a For example, if the color order index value is 1 , then the next object added to the axes uses the first color in the ColorOrder matrix. camroll(ax,dtheta) operates on the axes identified by the first argument, ax . Accelerating the pace of engineering and science. 'camera' (default) — Move in the coordinate system of the camera.dx moves left/right, dy moves down/up, and dz moves along the viewing axis. cameraTable input set the properties get(gca, 'Position') % get the position of the current axis Finally, remember down the road that (generally speaking) you can 'get' nearly every property of an object (figure, axes, lines, labels, etc.) Name is For example, By "camera position," it sounds like you want to adjust the elevation and the azimuth angle that you use to view the 3D plot.
