Create three matrices of the same size. Then plot them as a surface. The surface plot uses Z for both height and color. Specify the colors for a surface plot by including a fourth matrix input, C. The surface plot uses Z for height and C for color. Specify the colors using a colormap, which uses single numbers to stand for colors on a spectrum. When you use a colormap, C is the same size as Z.

Help Center Help Center. The plot is formed by joining adjacent points with straight lines. Surface plots are useful for visualizing matrices that are too large to display in numerical form and for graphing functions of two variables. Mesh plots are wire-frame surfaces that color only the lines connecting the defining points. Surface plots display both the connecting lines and the faces of the surface in color. This table lists the various forms. Low-level function on which high-level functions are based for creating surface graphics objects. These functions are useful when you need to restructure and interpolate data so that you can represent this data as a surface. The mesh and surf commands create 3-D surface plots of matrix data. If Z is a matrix for which the elements Z i,j define the height of a surface over an underlying i,j grid, then.

NumScaleLevels — Number of scale levels per octave 4 default integer scalar, greater than or equal to 3. The ZData property of the surface object stores the z -coordinates. Larger number of matlab surf result in finding larger size blobs.

Name-value arguments must appear after other arguments, but the order of the pairs does not matter. Before Ra, use commas to separate each name and value, and enclose Name in quotes. Strongest feature threshold, specified as a non-negative scalar.

Create three matrices of the same size. Then plot them as a surface. The surface plot uses Z for both height and color. Specify the colors for a surface plot by including a fourth matrix input, C. The surface plot uses Z for height and C for color. Specify the colors using a colormap, which uses single numbers to stand for colors on a spectrum. When you use a colormap, C is the same size as Z. Add a color bar to the graph to show how the data values in C correspond to the colors in the colormap. Specify the colors for a surface plot by including a fourth matrix input, CO.

To use different intervals, specify a four-element vector of the form [xmin xmax ymin ymax]. To use the same interval for both u and v , specify uvinterval as a two-element vector of the form [min max]. To use different intervals, specify a four-element vector of the form [umin umax vmin vmax]. For example, '-r' specifies red lines.

Function Used to Create meshgrid Rectangular grid in 2-D and 3-D space griddata Interpolate scattered data griddedInterpolant Interpolant for gridded data scatteredInterpolant Interpolate scattered data. Specify the colors for a surface plot by including a fourth matrix input, CO. Example: "--or" is a red dashed line with circle markers. For a custom color, specify an RGB triplet or a hexadecimal color code. Fix this issue by increasing the 'MeshDensity' to 40 in the second plot. Use a different color for each edge based on the values in the CData property. LineSpec — Line style, marker, and color string scalar character vector. Data Types: single double int8 int16 int32 int64 uint8 uint16 uint32 uint64 categorical datetime duration. Set the NumOctaves parameter appropriately for the image size. Example: 'Marker','o','MarkerFaceColor','red'. Select a Web Site Choose a web site to get translated content where available and see local events and offers.

El color predeterminado de [0 0 0] se corresponde con bordes negros. Function Used to Create meshgrid Rectangular grid in 2-D and 3-D space griddata Interpolate scattered data griddedInterpolant Interpolant for gridded data scatteredInterpolant Interpolate scattered data. The color varies across each edge by linearly interpolating the color values at the vertices. Other MathWorks country sites are not optimized for visits from your location. Surface and Mesh Plots Representing gridded data as surface and mesh plots. Search MathWorks. Plotting interval for u and v , specified in one of these forms: Vector of form [min max] — Use the interval [min max] for both u and v Vector of form [umin umax vmin vmax] — Use the interval [umin umax] for u and [vmin vmax] for v. Van Gool. Example: "--or" is a red dashed line with circle markers. Increase this number to detect more blobs at finer scale increments.
