isovalue), where V is a three-dimensional array representing the value of a scalar field. At this point, the isosurface function automatically creates a grid and uses the default coordinate vector.5. fplot3函数
Consider a two-dimensional input array,A: sum(A,1)operates on successive elements in the columns ofAand returns a row vector of the sums of each column. sum(A,2)operates on successive elements in the rows ofAand returns a column vector of the sums of each row. ...
If a matrix is N-dimensional, MATLAB represents the data in N-major order. For example, consider a three-dimensional array having dimensions4-by-2-by-3. Although you can visualize the data as: MATLAB internally represents the data for this three-dimensional array in this order: ...
Consider a two-dimensional input array, A: sum(A,1) operates on successive elements in the columns of A and returns a row vector of the sums of each column. sum(A,2) operates on successive elements in the rows of A and returns a column vector of the sums of each row. sum returns...
Magnitude-squared coherence estimate, returned as a vector, matrix, or three-dimensional array. w— Normalized frequencies vector Normalized frequencies, returned as a real-valued column vector. f— Frequencies vector Frequencies, returned as a real-valued column vector.More...
bar3(Z)绘制三维条形图,Z中的每个元素对应一个条形图。如果z是向量,y轴的刻度范围是从1至1ength(Z)。如果z是矩阵,则y轴的刻度范围是从1到z的行数。 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 1...
A two-dimensional array is effectively a table of data, not restricted to numeric data. If arrays are stacked in the third dimension, then they are three-dimensional arrays. Matrices are two-dimensional arrays that contain only numeric data or mathematical expressions where the variables of the ...
3.help :这也是最重要的一个函数吧。在想要知道某个函数的相关说明的时候,可以使用help 函数名来获取,当然也可以使用“doc ..”打开帮助文档。 使用系统命令: 输入和输出命令 向量,矩阵和阵列命令: 绘图命令: ---实例说明部分--- 矩阵基本知识: >> a=rand(2,3) %随机生成2*3的矩阵 a = 0.2785 ...
