I want to create string of characters from variable name And use it as a name of an excel file. It's easy to create a single string but I want to write a function that generalizes this situation. For my part: I have a signal that I have to cut into several windows, for each wind...
able to run with user input'd parameters (any combination of the five), and then the code to load the ones that were not specified. Since I don't know which parameters will be input, I need a way to check, and the best I can come up with is based on the name of the v...
Add a legend, and notice that the legend labels match the variable names. Get x = linspace(0,6,20); y1 = cos(x); y2 = sin(x); tbl = table(x,y1,y2); stairs(tbl,"x",["y1","y2"]); % Pad x- and y-axes, and add legend axis padded legend Alternatively, you can omit...
stem(tbl,yvar) plots the specified variable from the table against the row indices of the table. If the table is a timetable, the specified variable is plotted against the row times of the timetable. To plot one set of y-values, specify one variable for yvar. To plot multiple sets of...

上面所有函数都可以用“help funcName”或“doc funcName”命令查看帮助,参考Matlab R2012a帮助文档“MATLAB/Functions”。 当前文件夹(Current Folder)和搜索路径(Search Path): Matlab之所以强大,很重要的原因是它实现了很多数学算法,也就是有一个庞大的函数库。和其他编程语言一样,这些函数以实现文件或源文件形式存...
MATLAB adds variableato the workspace and displays the result in the Command Window. a = 1 Create a few more variables. b = 2 b = 2 c = a + b c = 3 d = cos(a) d = 0.5403 When you do not specify an output variable, MATLAB uses the variableans, short foranswer, to store ...
scatter(___,Name,Value) modifies the scatter plot using one or more name-value arguments to set properties. For example: scatter(x,y,"LineWidth",2) creates a scatter plot with 2-point marker outlines. scatter(tbl,"MyX","MyY","ColorVariable","MyColors") creates a scatter plot from data...
Variable names: A string, character vector, or cell array. A pattern object. "A" or 'A'— A variable named A ["A","B"] or {'A','B'}— Two variables named A and B "Var"+digitsPattern(1)— Variables named "Var" followed by a single digit Variable index: An index number that...
