MATLAB Function Reference (Volume 2: Graphics)

Surface PropertiesVertexNormals vector or matrixSurface normal vectors. This property contains the vertex normals for thesurface. MATLAB generates this data to perform lighting calculations. You cansupply your own vertex normal data, even if it does not match the coordinatedata. This can be useful to produce interesting lighting effects.Visible{on} | offSurface object visibility. By default, all surfaces are visible. When set to off,the surface is not visible, but still exists and you can query and set itsproperties.XDatavector or matrixX-coordinates. The x-position of the surface points. If you specify a row vector,surface replicates the row internally until it has the same number of columnsas ZData.YDatavector or matrixY-coordinates. The y-position of the surface points. If you specify a row vector,surface replicates the row internally until it has the same number of rows asZData.ZDatamatrixZ-coordinates. Z-position of the surface points. See the Description section formore information.2-493
