Dec 6, 2021 · Matlab中将文本文件中的混合数据块导入表或元胞数组 CSDN-Ada助手: 哇, 你的文章质量真不错，值得学习！不过这么高质量的文章, 还值得进一步提升, 以下的改进点你可以参考下: (1)使用更多的站内链接；(2)提升标题与正文的相关性；(3)增加条理清晰的目录。C = xor (A,B) performs a logical exclusive-OR of inputs A and B and returns an array or a table containing elements set to either logical 1 ( true) or logical 0 ( false ). An element of the output is set to logical 1 ( true) if A or B, but not both, contains a nonzero element at that same location. Otherwise, the element is set to 0.此 MATLAB 函数 是逻辑值 1 的速记形式。 ... T = true(sz) 是一个由逻辑值组成的数组，其中大小向量 sz 定义 size(T) ... This MATLAB function returns the piecewise expression or function pw whose value is val1 when condition cond1 is true, is val2 when cond2 is true, and so on.
Note that functions are not called in the base workspace. Functions that access the current non-lexical workspace (this is very rare) will therefore not work as expected. For example, matlab.truth = 42, matlab.exist('truth') will not find the truth variable. Use matlab.evalin('base', "exist('truth')", nargout=1) instead in this case.Import text data as a string data type, and then create import options by specifying the TextType name-value pair. opts = detectImportOptions ( 'outages.csv', 'TextType', 'string' ); Specify which variables to import using readtable, and then show a summary. The data type of the selected variables is now string.
Description. while expression, statements, end evaluates an expression , and repeats the execution of a group of statements in a loop while the expression is true. An expression is true when its result is nonempty and contains only nonzero elements (logical or real numeric). Otherwise, the expression is false.
Oct 28, 2017 · unique函数主要用来提取矩阵或者向量不同的元素的，言下之意，返回的矩阵中不存在相同的元素。前面这句话只在不添加额外的条件时成立，若是添加了rows条件就是返回不同的行。 以下是最常用的几种形式： 1）C = unique(A) 返回矩阵C中不存在相同的元素，并且是一个n×1的向量，该向量是从小到大 ...If a figure does not exist, then MATLAB ® calls the figure function to create one. example. c = uicontrol (Name,Value) creates a user interface control with property values specified using one or more name-value pair arguments. For example, 'Style','checkbox' creates a check box. c = uicontrol (parent) creates the default user interface ...An alternative to verifyTrue is the verifyReturnsTrue method. verifyTrue runs faster and is easier to use, but verifyReturnsTrue provides slightly better diagnostic information. In this …A givennumber is even or odd for this we use & operator. if any number is odd it must have right most bit 1. example: int i=5; binary form i= 0101. now use & operator. int j=i&1; [0101&1]//. here j have 0001; Reference : Check number even or odd without using modulo operator.

The biggest technical difference between MATLAB and Python is that in MATLAB, everything is treated as an array, while in Python everything is a more general object. For instance, in MATLAB, strings are arrays of characters or arrays of strings, while in Python, strings have their own type of object called str .

syms x eqn = sin (x) == 0; [solx,parameters,conditions] = solve (eqn,x, 'ReturnConditions' ,true) solx = π k. parameters = k. conditions = k ∈ Z. The solution π k contains the parameter k, where k must be an integer. The variable k does not exist in the MATLAB® workspace and must be accessed using parameters.Equality of Two Vectors. Create two vectors containing both real and imaginary numbers, then compare the vectors for equality. A = [1+i 3 2 4+i]; B = [1 3+i 2 4+i]; A == B. ans = 1x4 logical array 0 0 1 1. The eq function tests both real and imaginary parts for equality, and returns logical 1 ( true) only where both parts are equal.Lia = ismember (A,B) returns an array containing logical 1 ( true) where the data in A is found in B. Elsewhere, the array contains logical 0 ( false ). If A and B are tables or timetables, then ismember returns a logical value for each row. For timetables, ismember takes row times into account to determine equality.cT = true ( ___ ,"noCommunication") creates a codistributed array of logical ones without using communication between workers. You can use this syntax with any of the input arguments in the previous syntaxes. When you create very large arrays or your communicating job or spmd block uses many workers, worker-worker communication can slow down ...MATLAB functions for logical operations: all(): This determines if all array elements are nonzero or true. In this logical operation if all the elements of the array are non-zero then the output will be 1 (true) and If at least one of the elements is zero then the output will be 0 (false).Mar 29, 2021 · 关注. **matlab 报错 索引超出数组元素的数目 (1)。. **1：首先我们要明白这个报错的含义。. 索引超出数组元素的数目**（1）。. **要明白这个（1）的意思其实就是“你当前引用的数组元素的个数超过了这个数组定义的个数“。. 其实我相信读到这句话很多人是蒙蒙 ...MATLAB doesn't have conditional expressions, but in some situations you can get a similar effect by saying, e.g., var = cond*true_expr + (1-cond)*false_expr.Unlike C's conditional expression, this will of course always evaluate both true_expr and false_expr, and if cond happens not to be either 0 or 1 (note: false behaves like 0; true behaves like 1) you'll get crazy results.I would like to extract information contained in a 'true color' image. I explain myself a little bit. The attached image ('17p.png') is the vertical displacement in …
To check whether the condition A == B is always mathematically true for all values of variables in A and B, use isAlways(A == B). If one of the input arguments is a symbolic type and the other input is a MATLAB ® numeric type with the same value, then isequal returns logical 0 ( false ) because the inputs do not have the same data type.
Array Comparison with Relational Operators. Relational operators compare operands quantitatively, using operators like “less than”, “greater than”, and “not equal to.”. The result of a relational comparison is a logical array indicating the locations where the relation is true. These are the relational operators in MATLAB ®.

Changing the size and shape of the figure causes a change in the size and shape of the axes. The axes might select new axis tick mark locations as well. f = gcf; f.Position (3) = f.Position (3) * 0.67; Reshaping the axes to fit into the figure window can change the aspect ratio of the graph.Equality of Two Vectors.
