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.

Help Center Help Center. To use the same interval for both x and y , specify xyinterval as a two-element vector of the form [min max]. 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. Use this option after any of the previous input argument combinations. Use this option after any of the input argument combinations in the previous syntaxes. Use fs to query and modify properties of a specific surface. Specify the plotting interval as the second input argument of fsurf.

Input Arguments collapse all X — x matlab surf matrix vector. An RGB triplet is a three-element row vector whose elements specify the intensities of the red, matlab surf, green, and blue components of the color. You can now represent the values of Z with respect to X and Y.

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 function plots the values in matrix Z as heights above a grid in the x - y plane defined by X and Y. The function uses the default direction for the light source and the default lighting coefficients for the shading model. This sets the color data for the surface to be the reflectance of the surface. Because of the way surface-normal vectors are computed, surfl requires matrices that are at least 3-by This produces different results from the default colormap-based lighting method. Specify the 'light' object as the last input argument. Specify the axes as the first input argument.

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. The surface plot uses Z for height and CO for color.

Tipos de datos: single double int8 int16 int32 int64 uint8 uint16 uint32 uint64 categorical datetime duration. For example, 'FaceAlpha',0. Create a semitransparent surface by specifying the FaceAlpha name-value pair with 0. Use fs to query and modify properties of a specific surface. Vector of form [xmin xmax ymin ymax] — Use the interval [xmin xmax] for x and [ymin ymax] for y. Alternatively, you can specify some common colors by name. When you use truecolor, if Z is m -by- n , then CO is m -by- n -by Data Types: single double int8 int16 int32 int64 uint8 uint16 uint32 uint64 categorical datetime duration. The function plots the values in matrix Z as heights above a grid in the x - y plane defined by X and Y. Centro de ayuda Centro de ayuda. Then plot them as a surface. For a full list, see Surface Properties. Strongest feature threshold, specified as a non-negative scalar.

Given a matrix, and optionally the grid of X-axis and Y-axis values, it is possible to create a contour plot in R with the contour function. The nlevels argument controls the number of contour levels to be drawn. The default value is

Each octave spans a number of scales that are analyzed using varying size filters:. This object contains information about SURF features detected in a grayscale or binary image. Rectangular region of interest, specified as a vector. Help Center Help Center. Main Content. Off-Canvas Navigation Menu Toggle. You cannot use this value when the EdgeAlpha property is set to 'flat'. Use a different color for each edge based on the values in the CData property. Set the NumOctaves parameter appropriately for the image size. The intensities must be in the range [0,1] ; for example, [0. Specify the colors using truecolor , which uses triplets of numbers to stand for all possible colors. Open Live Script. Your variables are: X map pX pY pZ. La propiedad ZData del objeto de superficie guarda las coordenadas z. This table lists the named color options, the equivalent RGB triplets, and hexadecimal color codes.
