在弹出的“Import Data” 在“Import”窗口中,于左侧导入选项中选择“Matrix(矩阵)”,然后点击右侧的“勾”按钮,完成数据导入。关闭“Import”窗口,回到MATLAB主程序界面,在WorkSpace(工作空间)中可以看到新导入的矩阵变量,可以对其进行运算。每次关闭MATLAB程序时,工作空间中的变量会被清空。若需频繁使用该变量,建议将...
WL = Stream{:,2}; H = Stream{:,3}; V = Stream{:,4}; FlowRate = WL.*H.*V; StreamSorted = sortrows(Stream,"FlowRate") I am trying to take a 6x4 table called Stream from the .mat file and add my calculated value of FlowRate that is a 6x1 matrix and add this to my tab...
元胞数组是一种包含名为元胞的索引数据容器的数据类型,其中的每个元胞都可以包含任意类型的数据。元胞数组通常包含文本列表、文本和数字的组合或者不同大小的数值数组。通过将索引括在圆括号 () 中可以引用元胞集。使用花括号 {} 进行索引来访问元胞的内容。 创建对象 当要将数据放入一个元胞数组中时,请使用元...
Use the ismissing function to get a logical array of the table elements that contain missing values. Find the row and column subscripts for the elements that have NaN values. Finally, create a red background color style and add it to the cells in the table with NaN. styleIndices = ismis...
Use array operators instead of matrix operators for the best performance. For example, use .* (times) instead of * (mtimes). Example: funx = @(t) sin(2*t); funy— Parametric function for y coordinates function handle Parametric function for y coordinates, specified as a function handle ...
x-coordinates, specified as a scalar, vector, or matrix. The size and shape of X depends on the shape of your data and the type of plot you want to create. This table describes the most common situations. Type of PlotHow to Specify Coordinates Single point Specify X, Y, and Z as sc...
No. You cannot store a cell array inside a numeric matrix. I suggest that you use num2cell to transform the numeric data into a cell array that you can then vertcat or horzcat with the id cells Or consider using a table 댓글 수: 5 ...
legend(labels) sets the labels using a cell array of character vectors, a string array, or a character matrix, such as legend({'Jan','Feb','Mar'}). legend(subset,___) only includes items in the legend for the data series listed in subset. Specify subset as a vector of graphics obj...
“Matlab”是“MatrixLaboratory” 的缩写,中文“矩阵实验室”,是强大的数学工具。本文侧重于Matlab的编程语言侧面,讲述Matlab的基本语法,以及用Matlab语言进行程序设计。值得一提的是,Matlab从R2014a版本开始支持中文语言了! 1.基本概念 Matlab默认启动后界面: ...
