Bar3 (Z) draws a three-dimensional bar chart, one for each element in Z. If z is a vector, the scale of the y-axis is from 1 to 1ength (Z). If z is a matrix, the scale of the y-axis is from 1 to the number of rows in z. bar3(Y,Z)在Y指定的位置绘制Z中各元素的条...
y,z). where x and y are coordinate matrices, usually generated by the meshgrid function, that define the locations of mesh points in three-dimensional space. z is a matrix of the same size as x and y that defines
随着分析测量技术的发展,三维(Three-dimensional,3D)图谱的获取变得越来越容易.与传统的二维图谱相比,三维图谱由于增加了一个测定的维度,因而包含了更加丰富的待测物质的信息.因此,从理论上来说,基于三维指纹图谱对复杂体系的多个目标组分进行分析时能够获得更加准确,可靠的结果.三维荧光图谱(fluorescence3D spectrum,或exc...

sir I have a three dimensional matrix say A (122*13*14). In other way we can say it is concatenation of 14 matrix. But i want to make it two dimensional like B (1708*13) so that each matrix of dimension 122*13 should come one after another. I tried by the following code C=...
The meaning of plot3( ) is to plot the coordinates in three-dimensional space, the difference between it and plot is that more z-axis needs to be defined, to plot multiple sets of coordinates on the same set of axes, please specify at least one of X, Y, or Z as a matrix, and ...
(1) mesh(x,y,z): draw a three-dimensional grid graph, x, y, z represent the coordinates of the three-dimensional grid graph on the x-axis, y-axis and z-axis, respectively. The color of the graph is determined by the matrix z. mesh(Z): Draw a three-dimensional grid graph, and ...
surface(X,Y,Z) creates a primitive, three-dimensional surface plot. The function plots the values in matrix Z as heights above a grid in the x-y plane defined by X and Y. The color of the surface varies according to the heights specified by Z. Unlike the surf function, the primitive...
Use the functions meshgrid and mesh to obtain a three-dimensional plot of the function z=2xy/(x2+y2)forx=1:0.1:3andy=1:0.1:3 Redraw the surface using the function surf, surfl, and contour.1.12. An iterative equation for solving the equation x2−x−1=0 is given by xr+1=1+(...
something else in the computation. For example, suppose you want to temporarily replace NaN values with zeros, perform some computation, and then put the NaN values back in their original locations. In this example, the computation is two-dimensional filtering usingfilter2. You do it like this...
